Vanishing cursor problem

new imac 24' with a vanishing cursor problem, once or twice a day my cursor vanishes sometimes I can get it back by hitting the force quit shortcut keys at which point it will appear in the force quit dialog box, sometimes this does not work, at which point I have to reboot by holding down the power button, while in the force quit dialog box without the cursor visible i can use keyboard to quit all open apps and relaunch the Finder this has no effect.
uplugging and replugging has no effect, plugging into a different port has no effect, using two different usb mice has no effect.
I am using a logitech laser mouse that works perfectly on two other macs, the problem occurs with or without the logitech software running and also occured using the steermouse mouse driver.
all software appears to be up to date using software update ect.
cursor does not just become invisible, panning madly around with the mouse produces no effect in terms of opening the dock or whatever.
Help please!

Try posting in the MacBook Pro forum. We in the old G4 Tower forum are not familiar enough with the new systems to give out any advice!
Cheers!

XY Graph Cursor Problem in Labview 7.1.1?

Hallo,
I am using Labview 7.1.1 and I am facing one problem with XY graph cursor. If I am moving cursor in one graph, I am expecting same movement in another Graph. But when I move cursor in Graph1, cursor in second graph moves but not to exact X value of Graph1.
Property of Cursor in both graphs must be "Lock to Plot"
If any body knows about this please let me know ASAP. I am attaching example VI for your reference.
Thanks,
Sashi

It's a curious effect. Probably the floating point coordinate is sensitive to the exact pixel alignment (I mean that this would not happen if we had for example 1 pixel per point in the X direction).
Anyway, if you use Cursor Index instead (which is an integer) the behaviour is as expected.

ResultSet wihtin ResultSet but causes cursor problem?

I have a SQL error when running the code below:
while(rs0.next()){ ...
String s= rs0.getString(1);
ResultSet rs=null;
rs=getResult1(aConnnection, s);
/*statment is created in the function and ResultSet returned */
while(rs.next()){ ...
rs.close();
rs0.close();
Error: java.sql.SQLException: ORA-01000: maximum open cursors exceeded
The database setting is 200 cursors
and rs0 has 300 records, rs has only one record each time. I thought there should be only 2 cursors involved, do not know how can get so many.
Could some one help with my question?
Thanks in advance,
YM

Rethink your design.
If you let a method create a statement and a resultset, but return only the resultset, then there's no possibility to close the statetement.
I would create the statement outside the method, pass it to the method to do the query and return the resultset, but control the statement in my calling code.
So in your example you would hold references to 2 stattement just the same way like to their resultsets and close them all together.
This is more clean, and maybe will solve your cursor problem.
If you should come to the result that you would really need more open cursors (if your app runs on many clients at the same time, it could), there must be a DBMS configuration for increasing this limit.

Strange flashing cursor problem

Hi,
I've just finished installing Vista 32bit on my Macbook Air (1.6) and its working fine apart from one small problem - when starting up it freezes on a black screen with a flashing cursor for 2-4 mins and then will start loading Vista fine. Once in there is no problem and its stable and what not. I have had a look at some on the articles on here and other forums and the flashing cursor problem usually refers to when people try to first install a MS OS and not once one has been installed successfully.
I only have to boot into Vista every now and then and only for a few minutes at a time so I usually spend as much time in Vista as it does loading.
Any help appreciated.

Cs5 Brush cursor problem, on MacBook pro, tried the latest update, and the genious dude had no idea of what to do! Apple any fix?

Additional Info - after working on this problem for 4 hours, I shut my laptop in frustration and took a break. 1 hour later I opened my mac and the cursor had magically returned. No restart, no power on/off - nothing. Frustration. If anyone else has had this happen and has actually fixed the problem let me know. I'm sure it will reoccur.

Brush Cursor Problem

Hello, I've been experiencing a weird brush cursor issue and I haven't been able to find anything online to fix it.
This cursor problem is different from the "chunk of cursor missing upon resizing" issue that so many people have had.
In Photoshop, when I resize my brush using the "[" and "]" keys, I will often see my cursor get distorted. It will very briefly appear to the right of where the cursor should be and it will look kind of oblong. Another distortion that occurs is the cursor very briefly becomes a half circle that is a bit larger than the cursor should be. This usually happens between 150px and 250px size and occurs with all brushes.
I'm also experiencing a distortion when I move the brush cursor over to the panels section. This distortion appears (again, very briefly) as a broken up horizontal line just above the brush cursor. Also, within this line, I can see the regular pointer arrow cursor. Sometimes I see two arrow cursors within the line and other times just one. This happens with all brushes of size 500px or less.
I have updated my video card drivers to the latest version and I have updated my Photoshop with the latest patch.
I use Photoshop CS5 64-bit, Windows 7 Home Premium 64-bit, and a Toshiba Satellite L655-S5157 with an Intel(r) HD Graphics video card.
I heard about someone with a problem somewhat similar to mine and he said he fixed it by manually deleting his preference files. He had tried doing the shift+alt+ctrl on startup to delete his preference files, but it didn't fix the bug (I tried it too and it didn't work for me either).
I would like to try manually deleting my preference files, but I just don't know where they are.
Thanks for any help.

For you (or anyone reading this thread), try to get a machine with an embedded ATI or nVidia display interface.
Intel seems to be coming out pretty strong in the laptop market because they offer embedded GPUs in their chipsets, but Intel has a LONG way to go to get their OpenGL implementations up to par. What I don't understand is that they've been known for having relatively poor OpenGL implementations for years now. It's not like they're a small company who can't afford to fund a good development staff.
To this day I'm still fighting Intel-specific problems seen by people running my own OpenGL software, where ATI and nVidia implementations are rock solid. Stuff that's documented - such as handing off an OpenGL context between threads - just fails utterly with an Intel driver/GPU.

Cursor Problems in Adobe Edge

Hi!
I have this problem.
I opened an Adobe Edge working file, run it and there are cursor problems in the latest Adobe Edge version. I was doing a drag and drop animation. Cursor problems did not exist in the older Adobe Edge version. I had to install the latest Adobe Edge Animate as the previous version had expired. This cursor problems of going hay wire after running it from the working file, has been going on for a few animations. And it takes more time and effort for me to rectify and debug the errors before continuing with my work. By the way, the .html from the previous Adobe Edge version works alright. It is only when I want to edit the working file in the newer Adobe Edge version, that it gives me all these problems.
i hope someone will help me and thank you for your time.

Hi OrionsEdge,
I'm able to solve the problem. I looked through the codes and tried changing those parts which require the symbols' position to be changed through trial and error. If i'm not mistaken, it is related with the CSS.. it is tedious, but yeah, just change a part of the symbols' position first and try out the whole animation. observe and note down what are the changes. It will help you alot in your future code editings of the animations.

10.8.2 cursor problems

I am having terrible cursor problems after I installed 10.8.2. After starting the computer, the cursor refuses to move or jumps around, often the screen will resize. I have run the Disc Utility but that does nothing.

Yeah, I'm running OS X Server also on a Mac Mini and from my experiences, the PCs in the household couldn't connect via SMB to the Mac Mini until I set the Workgroup and Netbios Name in the WINS tab in Network on the Mini after a reboot.
Did any hardware change? Like maybe the router was replaced with a different brand and the Konica isn't getting the correct IP address?

Libretto W100 cursor problems

Hi,
I have lots of cursor problems on a new Libretto W100. Using the cursos field on the display it move it in exactly the opposite direction on the top screen. So I go to the right-below, the cursor moves in left-up direction. The only way I found to stop this problem is a complete reboot. And then it works OK, but when I close the lid and leave it alone for for example two hours, come and activate it the problem reappears. I especially not even touching the screen(s) to avoid confusing the machine. But I can consistently reproduce it.
Very annoying. Any one seen this and/or has a solution?
Regards,
Wim.

I found that the screens work properly after updating the various software updates on the toshiba download site. It is not very clear on the site which ones are essential but I used the registry patch and the software suite upgrade and things are better. Only remaining problem I have is that the touch pad no longer works- anyone got a solution for that?

Strange Cursor Problems

Hi everyone,
I have been having a lot of strange cursor manifestations happening after I reformated my computer and reinstallled the Adobe Suite. However, the only problems that pop up seem to be in Photoshop. I'll try my best to explain...
Whenever I adjust the size of the of a brush or switch between tools (like the clone stamp, healing brush, eraser, brush) or sample an area, either the brush cursor manifests twice so that I have to circles side by side or it turns into two lines on a diagonal that cross over each other (not crosshairs though).
I never had these problems before, and have no cursor problems outside of Photoshop. Anyone have an idea of what is going on, or even better, a solution?

Update your video driver from the web site of the maker of your video card. That's been known to solve problems such as what you're describing.
What video card do you have, by the way? nVidia?

Photoshop CC Vanishing cursor and freezing tools.

Any fixes coming for PSCC when the cursor vanishes (Don't say it's an Apple prob, because it only happens in PS and all 6 of my machines.) Also the tools freeze quite often and won't come back until I touch the desktop. Then PS plays catch up doing every click or hit I happen to hit in frustration. Help so I don't feel bad paying as little as I do per month fo this. Reinstalled it twice from a clean install. This is not a release ready product. BTW I have been using PS since 1994 to color comic books and with photography.

Yep, I remember you. (but I haven't seen Jeromy in a few years)
The disappearing cursor bug in MacOS can affect any program. Unfortunately we don't know all the details of the bug, but Apple is well aware of the problem.
For the freezing/event queueing problem: we're trying to get disk images that can reproduce it, so we can set up a duplicate system here to reproduce it. It's something we're going to have to debug for a while to figure out the cause. A few users have said that using different versions of the Wacom driver made the problem go away, or at least happen a lot less often.

Missing Cursor problem in Pages still exists

Beginning with page 97 of a document you cannot place the cursor at the bottom of the document anymore.
There already is an archived discusion on it but I don't find any further hints whether it is now a bug accepted by Apple:
https://discussions.apple.com/thread/2695065?start=0&tstart=0
I can reproduce this problem with all my books written with pages and without any import from other software. And I hope to continue to write books with Pages so I desperately hope that this will be fixed soon.
Is there any further hint available?
Thanksalot

Again, thank you for the quick answers. Of course there are several work arounds possible. As speed is crucial to me writing books and as I layout them including a lot graphics right from the beginning I would have to change my way of working just because of a bug. And, isn't it is a Mac and not a PC? The bug is older than 18 months - that is not very promising. From our development of the CONSIDEO MODELER we are used to fix any bugs within 3 months. What is promising, is that the documents can be edited with no problems on the iPad. However, as the iCloud for the exchange of iWorks documents between OS X and iOS is still a bad joke I am not satisfied. Maybe Apple can improve both, the iCloud functionality and Pages.
Fingers crossed

Open cursors problem- j2ee + oracle 10g

Hi,
I am using EJB on sunOne application server 8.1., Oracle 10g DB.
EJB container connects to Oracle DB through a set of connection pools.
BMP for all entity beans.
I have about 160 PL/SQL functions that make up the business logic of the online application. everytime the application runs, I get an increasing number of open cursors, including some of the ones that are explicitly closed within PL/SQL (inspection with sys.v_$open_cursor).
I made sure all CallableStatements, PreparedStatements, RecordSets within the beans are closed and set to NULL. All PL/SQL functions use explicit cursors, so every select statement is managed within a cursor which is explicitly closed when the function finishes with it.
From v$open_cursor, I identified the sessions with the cursors still open, and issued (ALTER SYSTEM KILL SESSION �sid, #serial�) for each of the sessions (this is done via a PL/SQL function for all inactive sessions).
These sessions have state INACTIVE, and wait_class IDLE. This has Killed all sessions, but I was not able to use the application anymore. I suspect by killing those sessions we have also caused the connections between EJB container and the Oracle DB. The only way to use the application now is to stop and restart the sunONE domain � this is very inconvenient.
Has anyone encountered a similar problem? any suggestions to reduce or eliminate the open cursors number? Please help.
Thank you all

Maybe you can try to have a smaller steady-pool-size and idle-timeout-in-millis for your connection pools.
Also, if that's at all possible, have smaller number of connection pools being shared by more apps.
Just my 2c.
thanks.

Amount of open cursor problem

I am trying to display a tree-like data with a varchar2 field called ancestor indicating its family nodes, e.g. 1:2:5:16. A quick solution would be recurssion:
procedure data_list(id in number default null) as
cursor c1 is select * from table1 where ancestor is null;
cursor c2 is select * from table2 where get_parent(ancestor) = id;
-- get_parent(varchar2) is a function return parent id of current data.
if (id is null) then
-- display root nodes
-- open c1 and print out data
-- then recursively call itself to print out its children
data_list(id);
close c1;
else
-- open c2 and print out data
-- then recursively call itself to print out its childen
data_list(id);
close c2;
end if;
end data_list;
======================
As you notice, the problem is that if the tree is too high (or too deep) the amount of cursors being open simultanously might be huge, which will definitely degrade the performance of the server, especially under multiuser environment.
Does someone here have better solution for this problem?
Thanks.

You probably want to start by looking into Oracle's hierarchal query support with the CONNECT BY clause and the SYS_CONNECT_BY_PATH function. Grabbing a quick example from the Oracle SQL Reference http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/functions121a.htm#1038139
SELECT LPAD(' ', 2*level-1)||SYS_CONNECT_BY_PATH(last_name, '/') "Path"
   FROM employees
   START WITH last_name = 'Kochhar'
   CONNECT BY PRIOR employee_id = manager_id;
Path
/Kochhar
   /Kochhar/Greenberg
     /Kochhar/Greenberg/Faviet
     /Kochhar/Greenberg/Chen
     /Kochhar/Greenberg/Sciarra
     /Kochhar/Greenberg/Urman
     /Kochhar/Greenberg/Popp
   /Kochhar/Whalen
   /Kochhar/Mavris
   /Kochhar/Baer
   /Kochhar/Higgins
     /Kochhar/Higgins/GietzNote that hierarchal queries work very well when you have tree data. If you actually have a graph, it starts to get more complicated.
