Strange/unusual behaviour of New-ish(Old white style) Macbook
I got my Macbook the same week the new ones came out, so its not very old.
Since day 1, sometimes when i turn it on the green light from the built in camera comes on, and wont go off until shut down. This then makes photobooth and any application that needs the camera unusable, until i restart.
Also recently, its started taking ages to start up. I only have the factor 1GB installed, but before it was nippy.
Then, one day it wouldn't start at all. It just stayed on the blue screen and that was it. So i booted from disc and archived and installed leopard, and it starts up but its still very slow.
I've got Leopard Onyx so i delete caches and unused files regurlarly and i even ran an anti virus to see if anything was going on, but nothing.
Its 4 months old, and just frustrating to wait 3-4mins for it to start up properly. It used to be on 30 seconds or so, so any advice is great.
Its the 2.1Ghz, intel core 2 duo, 1GB RAM, 120G HDD.
Thanks in advance
How much of that hard drive is free? OS X needs at least 10% of the hard drive open at all times in order to function at its best. Have you used Disk Utility to repair permissions? If you open up Activity Monitor (Applications>Utilities) and look at All Processes, is any one program using a lot of CPU/RAM?
Also you don't need to shutdown your MacBook unless you've installed an update requiring it--or if it's being unusually difficult. Sleep mode consumes very little power and you won't have to wait for the machine to boot!

Strange screen behaviour on new imac
Have had the new imac for a couple of weeks now and all of a sudden the display has started behaving very strangely. Intermittently it is distorting - jagged lines and graphics screwed. Screen capture is linked here:
http://www.malw.co.uk/photos/screencap.jpg
Hope someone can help! Thanks.I was hoping I wouldn't have to do that. I've been on the phone for two hours to Applecare who have tried reinstalling OSX (archive mode?), PRAM reset etc. The computer is fine though in safe mode, which leads me to believe the problem might be software based? Their solution now is a complete reinstall so basically I have to spend not only time reinstalling but getting everything back in order - I have an 80gb itunes library and 20gb of photos for starters, plus a load of software I've installed. Anyway, before I have to take that rather drastic route, hopefully someone might come up with something I haven't tried yet.

Strange LOV behaviour in new rows (UIX)
Hi all,
we are using UIX for a JHS implementation project and came across a "JHS-00107: Table data are out of date, please requery" error while testing our JHS-generated forms. The problem arises in a table with multi-row-insert enabled where some of the (hidden) fields are already filled in by default (using the application structure -> view object editor). If we then select a value in the LOV and it is returned to the base page, the error is generated and the selected LOV value does not appear. Also, the row is marked dirty and asks for submission if I try to navigate to another page afterwards.
If we leave out the defaults, no error is generated.
Is there a workaround possible for this problem, as we would very much like to keep the default values in there ?
Also (but this is not really important to our case), an LOV always seems to return its selected value to the upper new row, even if a second or third new rows LOV button was used.
Best regards,
BenjaminSandra,
here's my scenario:
+ I unzipped the jhsdemo, adapted connection settings for my db and set the paths in appstructure files to the path i unzipped to
+ In the model project, I extended the Subordinates viewobject with the DepId attribute of the Employee entity object.
+ In the appstructure file of the viewcontrollerinternal project, I set use table range to false, enable insert multiple rows and set the new rows property to one for the subordinates group (subgroup of employees). I also added an LOV to this group for selecting the Department.
+ using the JHS viewobject property editor for the subordinates group, i set the display and display in tables value for FirstName to hidden and set a default value '${bindings.EmployeeFirstName}' for the same column.
+ Finally, I reran the JHS app generator
in this case, if I select a department using the LOV, after returning from the LOV popup, nothing changes (so the LOV value is not shown on the page)
If I set the display to true again and do the same for the EmpId attribute (hiding it and filling in '${bindings.EmployeeId}', which is the Id of this subordinates manager), the "JHS-00107: Table data are out of date, please requery" error appears as soon as I try to select a value from the LOV.
I guess the second case means the error has something to do with the foreign key relationship which I try to give a default value. I think for this particular situation (entering a default value of the manager), JHS would take care of the FK link automatically by itself, but at least in the first case the LOV doesn't really do what users might expect ?
Best regards,

Old 2.4 white versus new 2.1 white Macbook
Hi there, I'm in the market for a new (or old?) MacBook.
I need Firewire for music recording purposes, so I'm looking at either today's white 2.1ghz MacBook or yesterday's white 2.4ghz MacBook.
They are currently available at various places for around the same price.
The older one has 2.4ghz, but 667mhz bus
the newer one has 800mhz bus, but slower 2.1 ghz processor.
Which one is the more powerful machine?
Thanks for your help!Thank you Dave - i had a hunch that might be the case, but since they have obviously taken the white 2.4's off this site it is difficult to tell on the resellers sites exactly what specs they are.
Basically I guess what I'm asking is this: what is new about the white macbook listed here:
http://store.apple.com/uk/browse/home/shop_mac/family/macbook?mco=MTE3MjE
if anything? (there's a "new" listed above it, even if it is not the new aluminium model)
Because to me it just looks like the old 2.1ghz macbook with a price INCREASE - am I right.
Kappy - I think I've made it quite clear which laptop I'm talking about - it's a white MacBook, listed on the MacBook page of the Apple store (not the aluminium ones). While it is not technically a new design - it is listed there as "new". -

Strange memory behaviour using the System.Collections.Hashtable in object reference
Dear all,
Recently I came across a strange memory behaviour when comparing the system.collections.hashtable versus de scripting.dictionary object and thought to analyse it a bit in depth. First I thought I incorrectly destroyed references to the class and
child classes but even when properly destroying them (and even implemented a "SafeObject" with deallocate method) I kept seeing strange memory behaviour.
Hope this will help others when facing strange memory usage BUT I dont have a solution to the problem (yet) suggestions are welcome.
Setting:
I have a parent class that stores data in child classes through the use of a dictionary object. I want to store many differenct items in memory and fetching or alteging them must be as efficient as possible using the dictionary ability of retrieving key
/ value pairs. When the child class (which I store in the dictionary as value) contains another dictionary object memory handeling is as expected where all used memory is release upon the objects leaving scope (or destroyed via code). When I use a system.collection.hashtable
no memory is released at all though apears to have some internal flag that marks it as useable for another system.collection.hashtable object.
I created a small test snippet of code to test this behaviour with (running excel from the Office Plus 2010 version) The snippet contains a module to instantiate the parent class and child classes that will contain the data. One sub will test the Hash functionality
and the other sub will test the dictionary functionality.

d_CycleCount = 50000
'Add dummy data records to the child container with x amount of data For d_Count = 0 To d_CycleCount
Parent.ChildContainer("TEST_hash").InsertDataToHash CStr(d_Count), "dummy data"
Next
'Killing the parent when it goes out of scope should kill the childs. (Try it out and watch for the termination debug messages)
'According to documentation and debug messages not really required!

'According to documentation not really as we are leaving scope but just to be consistent.. kill the parent!

Memory released:Hi Cor,
Thank you for going through my post and took the time to reply :) Most apreciated. The issue I am facing is that the memory is not reallocated when using mixed object types and is not behaving the same. I not understand that .net versus the older methods
use memory allocation differently and perhaps using the .net dictionary object (in stead of the scripting.dictionary) may lead to similar behaviour. {Curious to find that out -> put to the to do list of interesting thingies to explore}
I agree that allocated memory is not a bad thing as the blocks are already assigned to the program and therefore should be reallocated with more performance. However the dictionary object versus hashtable perform almost identical (and sometimes even favor
the dictionary object)
The hashtable is clearly the winner when dealing with small sets of data.
The issue arises when I am using the hash table in conjunction with another type, for example a dictionary, I see that the dictionary object's memory is stacked on top of the claimed memory space of the hashtable. It appears that .net memory allocation and
reuse is for .net references only. :) (Or so it seems)
In another example I got with the similar setup, I see that the total used memory is never released or reclaimed and leakage of around 20% allocated memory remains to eventually crash the system with the out of memory message. (This is when another class
calls the parent class that instantiates the child class but thats not the point of the question at hand)
This leakage drove me to investigate and create the example of this post in the first place. For the solution with the class -> parent class -> child class memory leak I switched all to dictionaries and no leakage occurs anymore but nevertheless thought
it may be good to share / ask if anyone else knows more :D (Never to old to learn something new) -
Strange JFRAME behaviour under Jdk 1.5
I have the following extracted code :
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import java.awt.geom.*;
public class DrawPie extends JFrame{
private HashMap ColourMap=new HashMap();;
private HashMap DataMap=new HashMap();
private double Total_Val=0;
private int startAngle=0;
private int arcAngle=0;
public DrawPie(HashMap DataMap){
super ("Pie Chart Analysis");
this.DataMap=DataMap;
// System.out.println("DATAMap-->"+DataMap);
// getContentPane().setBackground(Color.white);
setSize(500,500);
setVisible(true);
public void paint(Graphics g){
super.paint (g);
Graphics2D g2 = (Graphics2D) g;
DrawPieChart(g);
This programme work fine under jdk1.4.2 or below at the time when the Jframe or windows is resized or icon minimised or maximised.
But when it was compiled using latest jdk1.5 , unexpected strange result happen , the pie chart draw using java 2d
g2.fill(new Arc2D.Double(30, 30, 200,200,startAngle,arcAngle
, Arc2D.PIE));
wil behaved strangely, the moment the JFrame or windows is resize or dragged.
The pie chart will disappear if the windows is resized , However if the window is minimised and restore back to normal size , pie chart will reappear and subsequently lost completely if the windows is dragged resulted in the size changes.
I was puzzled by this strange swing behaviour , any resized or windows minimise or maximise would not result in the lost of pie chart as long as the jdk is not 1.5 ! Was it due to swing fundamental changes incorporated in the latest release?
Any suggestion?
Thankok I see what you have done,
now a few tips in drawing something on your frame:
never override the paint method of your main Frame (like you did)
to draw something on it you simply override the contentPane's paint method
and to make your own contentPane you simply make one by making a new Class
that extends say JPanel and assign it as a contentPane of your Frame(like I did)
And in this Paint method you can draw whatever you like it will be properly uptated!!!
All the best keep up the good work!
ps. try the code bellow.
import javax.swing.*;
public class DrawPie1 extends JFrame {
private double Total_Val=0;
private int startAngle=0;
private int arcAngle=0;
private MyMainPanel mainPan;
public DrawPie1()
super ("Pie Chart Analysis");
mainPan = new MyMainPanel();
setContentPane(mainPan);
//public void paint(Graphics g) //Do not override the paint method of your main frame!!
// super.paint (g);
// Graphics2D g2 = (Graphics2D) g;
// g2.setPaint(Color.red);
// g2.fill(new Arc2D.Double(30, 30, 200,200,0,78
// , Arc2D.PIE));
public static void main(String args[])
DrawPie1 pie=new DrawPie1();
pie.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pie.setSize(400,300);
pie.setVisible(true);
//**** Second Class
import javax.swing.*;
import java.awt.*;
import java.awt.geom.Arc2D;
public class MyMainPanel extends JPanel
public MyMainPanel()
public void paint(Graphics g)
super.paint (g);
Graphics2D g2 = (Graphics2D) g;
g2.setPaint(Color.red);
g2.fill(new Arc2D.Double(30, 30, 200,200,0,78
, Arc2D.PIE));

Strange viewing behaviour on score page view on Logic 7.2.0 on MacBookPro
I recorded some sequences in Logic 7.2.0 on my MacBookPro and, seeing them in page view mode, I get a strange viewing behaviour: the staffs continue going straight on overshooting the "white delimited page zone". If I try to zoom out I can't obtain the "more pages view" option normally obtained.
If I reopen this song on the logic 7.2.0 situated in my G5 all is fine. Why?
Any idea?
Thanks
FulvioGuys, I think this problem has to do with the scale parameter of the instrument set being translated incorrectly on Intel/MPB (quite possibly affecting even the "ALL" instrument set, which has no adjustable parameters). Now, I don't have an Intel Mac or MBP, but based on my recent experiences in PPC and similar problems, plus what I've read here, I think I might be on to something...
I'm going to suggest that you guys who are having problems with staves going off the page to do the following test:
1) Open one of your problematic songs and view the score editor where the off-the-page staves are displayed
2) If you're using the "ALL" instrument set, read on. If not, go to #3 below.
ALL Instrument Set: if you're using this just to see a preliminary version of your score, close the score window, select ALL, and open the score editor. This forces the creation of a new instrument set. Do these staves go off the page? If not, you're good to go. But if they do go off the page...
a) go to your printer settings and make sure that you have valid settings there. This includes the printer type, page size, and scaling. If they're set to default values (like "most recent printer"), be sure to select an actual printer on your system.
b) open the Instrument Set parameters for the set that was created just before. Set the scale parameter to 200%, then make it 50%, then make it 100%. If my theory is correct, your music should now stay on the page.
3) If you're using a custom instrument set repeat steps a) and b) above. See if that clears up the problem.
I'd be curious to know if any of the above fixes the problem for you. Again, it's just a theory, but maybe it has legs...
Best,

Advance warning - Mail worked fine.
I had fits with the last link I posted. At first it worked fine, then all of a sudden, it quit working. I now have iCloud - iCal syncing, but iCal is read only. Not a real big deal since you can log onto iCloud using Safari and post a new event.
I finally gave up on Address Book because it kept creating multiple contacts, which if you tried to merge or delete the multiple contacts, the contacts were deleted. It also worked at first and then stopped working as it should. -
ISE 1.1.2 - strange GUI behaviour? bug?
Something has changed in GUI in the latest 1.1.2 version cause its not working properly.
In the first place I encountered an issue while adding new endpoint group.
I added some - then it refused to add new, rename old. I tried to add authorization profile and received such a notification (after 2 min of processing)
I patched the system (v3) and this problem disappeared but now I have another problem.
I added some authorization policies (in a number of 9) -> saved it and it show only part of it.
I can't add it againg cause it says its already created.
After restarting all the services I see only one policy (not even the defaults)
(tried different browsers - the same)
Has anyone had similar issues?
Should I downgrade to 1.1.1 ?
Its a pair of 3315.
After promoting the secondary to Administration role, I see 4 of the 10 policies and what is the most interesting the one (default) I deleted after installing the server.
I will deregister the pair and try them independently with different software version. (1.1.2patch3 vs 1.1.1patch5)
regards
Przemekthx for fast reply
- resizing - did solve the problem
I tried:
- opera - didn't work at all
- FF (18.0.1) - issue as described earlier
- IE 9 - the same
- IE 8 - the same
- chrome - the same
I have my lab NFR ISE 1.1.2 (standalone) and have no such dificulties with any browser. I'm starting to think it concerns deployment scenario with 2xISE
What is more I noticed sth strange after promoting ISE (only in Chrome).
In more details:
- I have 2xISE (gatemaster.domain.local, gatemaster2.domain.local)
After promoting gatemaster2 and accessing the GUI my main view was as the following
It seems to me that even though Im using gatemaster2, internal scripts refers to gatemaster,
I observed it only in chrome probably cause I installed Google Ch. after the promotion and it didn't have it cached.
Is your environment standalone?

New Monitor, Old Computer Compatibility
I have a new(ish) Acer monitor. It's only 17.5" apparently, but its native resolution is something like 1600 x 900 and 32-bit colour, though I think it can handle lower resolution if need be.
I have a Sawtooth with a Rage 128 Pro graphics card.
Will the latter be able to handle the former? I have the DVI cablery necessary to connect them, I'm just concerned that Sawtooth's antiquated graphics card won't want anything to do with the new monitor (even if my Intel Mac Mini can set it to a lower resolution as desired).
Additionally, the Sawtooth will be running OS 9 and will need to boot off an external hard drive or install CD.OK, thanks. The monitor worked after all. (Once I finally requisitioned it for the afternoon.)
Sawtooth is now running Mac OS 9.0.4 (found a copy on Macintosh Garden; my own CD is long since lost to the mists of time.)
Sawtooth briefly ran OSX 10.4.11 since I had to boot it off my external drive to reformat its internal drive (which was pulled from a PC; Windows NT format, and had some X86-friendly version of Linux on it). It was a somewhat aggravating experience trying to run Tiger on a 400 Mhz processor.
For some reason, it wouldn't boot off the install CD, though. (I booted it into OS 9.2.2 off the external drive and it mounted the install CD; it just wouldn't boot off it. Luckily, OS 9 doesn't need to boot off the CD to install.) I wonder why that is.
PS— Seems they redesigned the support forums. The old one was better. -

My new(ish) 30 day old Samsung S4 won't start. It was working normally this morning. Now it won't start. I take out my battery plug it back in, and then the screen displays "samsung galaxy 4" for like a good 3 seconds. Is there any way I can fix this?

Strange repaint behaviour with JList & Keyboard actions
Hi everyone,
This is my first post to the forum. You guys have been a great help in the past and I hope to contribute more in the future.
Anyways, I've encountered some strange repainting behaviour with a JDialog that uses a JList and a JButton. The dialog is fairly straight-forward and basically this is how it works (like an open file dialog - yes I'm implementing my own filechooser of sorts):
* JList lists a number of simple items that the user can select from.
* Once a selection is made, an Open button (JButton) is enabled.
* <ENTER> key is registered (using registerKeyboardAction()) with a JPanel which is used as the main content pane in the dialog.
* The user can either click on the Open Button or hit the <ENTER> key which then closes the dialog and runs whatever logic that needs to.
Now, the repaint problem comes in when:
1. User selects an item.
2. User hits the <ENTER> button
3. Dialog closes
4. User brings the dialog back up. This entails reloading the list by removing all elements from the list and adding new ones back in.
5. Now... if the user uses the mouse to select an item lower in the list than what was done in step #1, the selection is made, but the JList doesn't repaint to show that the new selection was made.
I didn't include a code sample because the dialog setup is totally straight-forward and I'm not doing anything trick (I've been doing this kind of thing for years now).
If I remove the key registration for the <ENTER> key from the dialog, this problem NEVER happens. Has anyone seen anything like this? It's a minor problem since my workaround is to use a ListSelectionListener which manually calls repaint() on the JList inside the valueChanged() method.
Just curious,
HuyOh, my bad. I'm actually using a JToggleButton and not a JButton, so the getRootPane().setDefaultButton() doesn't apply because it only takes JButton as an input param. I wonder why it wasn't implemented to take AbstractButton. hmmm.

Edited by: noregister on Oct 4, 2011 11:31 AMOh, my bad. I'm actually using a JToggleButton and not a JButton, so the getRootPane().setDefaultButton() doesn't apply because it only takes JButton as an input param. I wonder why it wasn't implemented to take AbstractButton. hmmm.

Strange JTable behaviour - everything is highlighted
Hello all,
im experiencing some strange JTable behaviour, and im not so sure why. When i run my program, the JTable appears, but all the cells are highlighted in advance. Also, i can now only select one cell at a time. I have set myTable.setSelectionModeListSelectionModel.SINGLE_INTERVAL_SELECTION); myTable.setCellSelectionEnabled(true);and my renderer code is below. I call the renderer by using the setDefaultRenderer method with(Object.class,myRenderer).
I have also changed isCellEditable to return true. If i dont use Object.class, and try to use my own custom class, the JTable is not all highlighted, but it doesnt seem to use myRenderer, and when i click on the header of Column A, all cells from column B and beyond become highlight, which is not normal behaviour. I thought the colum you selected should be highlighted.
Sorry for the long post, i hope the above makes sense...this is really quite bizzare, and im not so sure why this is happening. Thanks for any advice you can give, regards, Rupz

thanks for the reply - now the table isnt all highlight when loaded, but as for cell celection..thats a different matter. I did have myTable.setCellSelectionEnabled(true); but no, the cell behaviour is really, eally weird, quite hard to explain, but here goes.
If i try to select cell D1 and D2 - D1 is selected, D2, E2,F2 and so on become selected. If i try to add D3 to the mix, the entire row 3 is selected, and as soon as i let go of the mouse button, the entire table except row 1 gets selected. really really weird. Below is my tableModel and what i do to the table. Thanks for your help,
regards

// myCell temp = new myCell(new Integer(x+1));
// super.setValueAt(temp, x, 0);
for(int x =0 ; x < rows; x++)
for (int y = 0; y < cols; y++)
// we initialize it here
super.setValueAt(new myCell(rows,cols,("")),x,y);
mySpreadsheet = aSpreadsheet;
public boolean isCellEditable(int row, int column) {return true;}
