USB devices stop when ctrl key is pressed

We have a couple of Lenovo 3000 N100 notebooks that are exhibiting the same problem - with USB external mouse and keyboard attached, the "Ctrl" key on the notebook will kill the attached USB devices - the system gives a couple of audible warnings then the USB mouse will reappear - depressing the same key on the external USB keyboard does not give the same symptoms. Has anybody else had a similar problem? Very aggravating when trying to tag files etc..
Thanks,

I thought something was wrong with the bugbase, but apparently I just needed to "save" my communication settings (the website won't let you do anything else until then).
Bug filed is here: https://bugbase.adobe.com/index.cfm?event=bug&id=3613482
It's not something everyone will see, but when it happens the result is confusion and a buggy feeling application.

Determine if Ctrl key is pressed.

I want to perform some actions when handling Mouse Move event only when Ctrl key is pressed. Is there a way to determine pressed state of Ctrl key?

Hi Jonni,
I've attached a simple example VI that uses the Mouse Move event filter to check for mouse movement and calls user32.dll to check if CTRL key is pressed. I think that is what you are looking for.

Firefox freezes when ctrl + enter is pressed simultaneously

Firefox freezes when ctrl + enter is pressed simultaneously.

Hello,
Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
(If you're not using it, switch to the Default theme.)
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
Please report back soon.

How do I check if the ctrl key is pressed from within a mouseReleased actio

How do I check if the ctrl key is pressed from within a mouseReleased action?
      addMouseListener( new MouseAdapter() {
         public void mouseReleased( final MouseEvent e ) {
           // If ctrl button is held down and mouse is clicked, do something
         }};

Found it, I think
    e.isControlDown()

Default button being clicked multiple times when enter key is pressed

Hello,
There seems to be a strange difference in how the default button behaves in JRE 1.4.X versus 1.3.X.
In 1.3.X, when the enter key was pressed, the default button would be "pressed down" when the key was pressed, but wouldn't be fully clicked until the enter key was released. This means that only one event would be fired, even if the enter key was held down for a long time.
In 1.4.X however, if the enter key is pressed and held for more than a second, then the default button is clicked multiple times until the enter key is released.
Consider the following code (which is just a dialog with a button on it):
public class SimpleDialog extends JDialog implements java.awt.event.ActionListener
private JButton jButton1 = new JButton("button");
public SimpleDialog()
this.getContentPane().add(jButton1);
this.getRootPane().setDefaultButton(jButton1);
jButton1.addActionListener(this);
this.pack();
public void actionPerformed(ActionEvent e)
if (e.getSource() == jButton1)
System.out.println("button pressed");
public static void main(String[] args)
new SimpleDialog().show();
When you compile and run this code under 1.3.1, and hold the enter key down for 10 seconds, you will only see one print line statement.
However, if you compile and run this code under 1.4.1, and then hold the enter key down for 10 seconds, you will see about 100 print line statements.
Is this a bug in 1.4.X or was this desired functionality (e.g. was it fixing some other bug)?
Does anyone know how I can make it behave the "old way" (when the default button was only clicked once)?
Thanks in advance if you have any advice.
Dave

Hello all,
I think I have found a solution. The behaviour of the how the default button is triggered is contained withing the RootPaneUI. So, if I override the default RootPaneUI used by the UIDefaults with my own RootPaneUI, I can define that behaviour for myself.
Here is my simple dialog with a button and a textfield (when the focus is NOT on the button, and the enter key is pressed, I don't want the actionPerformed method to be called until the enter key is released):
package focustests;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.*;
public class SimpleDialog extends JDialog implements java.awt.event.ActionListener
private JButton jButton1 = new JButton("button");
public SimpleDialog()
this.getContentPane().add(new JTextField("a text field"), BorderLayout.NORTH);
this.getContentPane().add(jButton1, BorderLayout.SOUTH);
this.getRootPane().setDefaultButton(jButton1);
jButton1.addActionListener(this);
this.pack();
public void actionPerformed(ActionEvent e)
if (e.getSource() == jButton1)
System.out.println("button pressed");
public static void main(String[] args)
javax.swing.UIManager.getDefaults().put("RootPaneUI", "focustests.MyRootPaneUI");
new SimpleDialog().show();
and the MyRootPaneUI class controls the behaviour for how the default button is handled:
package focustests;
import javax.swing.*;
* Since we are using the Windows look and feel in our product, we should extend from the
* Windows laf RootPaneUI
public class MyRootPaneUI extends com.sun.java.swing.plaf.windows.WindowsRootPaneUI
private final static MyRootPaneUI myRootPaneUI = new MyRootPaneUI();
public static javax.swing.plaf.ComponentUI createUI(JComponent c) {
return myRootPaneUI;
protected void installKeyboardActions(JRootPane root) {
super.installKeyboardActions(root);
InputMap km = SwingUtilities.getUIInputMap(root,
JComponent.WHEN_IN_FOCUSED_WINDOW);
if (km == null) {
km = new javax.swing.plaf.InputMapUIResource();
SwingUtilities.replaceUIInputMap(root,
JComponent.WHEN_IN_FOCUSED_WINDOW, km);
//when the Enter key is pressed (with no modifiers), trigger a "pressed" event
km.put(KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_ENTER,
0, false), "pressed");
//when the Enter key is released (with no modifiers), trigger a "release" event
km.put(KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_ENTER,
0, true), "released");
ActionMap am = SwingUtilities.getUIActionMap(root);
if (am == null) {
am = new javax.swing.plaf.ActionMapUIResource();
SwingUtilities.replaceUIActionMap(root, am);
am.put("press", new HoldDefaultButtonAction(root, true));
am.put("release", new HoldDefaultButtonAction(root, false));
* This is a copy of the static nested class DefaultAction which was
* contained in the JRootPane class in Java 1.3.1. Since we are
* using Java 1.4.1, and we don't like the way the new JRE handles
* the default button, we will replace it with the old (1.3.1) way of
* doing things.
static class HoldDefaultButtonAction extends AbstractAction {
JRootPane root;
boolean press;
HoldDefaultButtonAction(JRootPane root, boolean press) {
this.root = root;
this.press = press;
public void actionPerformed(java.awt.event.ActionEvent e) {
JButton owner = root.getDefaultButton();
if (owner != null && SwingUtilities.getRootPane(owner) == root) {
ButtonModel model = owner.getModel();
if (press) {
model.setArmed(true);
model.setPressed(true);
} else {
model.setPressed(false);
public boolean isEnabled() {
JButton owner = root.getDefaultButton();
return (owner != null && owner.getModel().isEnabled());
This seems to work. Does anyone have any comments on this solution?
Tjacobs, I still don't see how adding a key listeners or overriding the processKeyEvent method on my button would help. The button won't receive the key event unless the focus is on the button. There is no method "enableEvents(...)" in the AWTEventMulticaster. Perhaps you have some code examples? Thanks anyway for your help.

I connect my mic with an M-audio mobile pre usb device. When I try to record, I can see that my voice is recording but can't hear it during playback.

I connect my mic with an M-audio mobile pre usb device. When I try to record, I can see that my voice is recording but can't hear it during playback. I tried different input and output settings but it didn't help. Any help will be appreciated.

Hear your microphone or instrument as you play and record (monitoring)
You can hear, or monitor, input from an instrument or microphone in GarageBand while you play and record. When you turn on monitoring for a track, you hear the musical instrument or microphone connected to the track’s input. Monitoring lets you hear yourself play so that you can hear the part you want to record as well as the rest of the project.
You can turn on monitoring for a Real Instrument track or Electric Guitartrack from the track’s header, or in the Track Info pane. Electric Guitar tracks always show their monitoring buttons, and you can show monitoring buttons for Real Instrument tracks using a menu command. You can use monitoring with feedback protection to avoid feedback while you play.
Hide
To turn on monitoring in the track header:
Choose Track > “Show Monitoring for Real Instrument Tracks.”Monitor buttons appear in the headers of Real Instrument tracks. On tracks with monitoring turned on, the button lights yellow.
Click the Monitor button in the header of the track you want to use.
HideTo turn on monitoring in the Track Info pane:
Double-click the header of the Real Instrument or Electric Guitar track you want to turn on monitoring for.The Track Info pane opens.
From the Monitor pop-up menu, choose one of the following:
Choose Off to turn off monitoring. You can hear your instrument only while you record.
Choose On to turn on monitoring and protect against feedback.
Choose On (no feedback protection) to turn on monitoring without feedback protection. If the input level is too high, it may cause feedback (especially if you are using a microphone and listening to your project through your computer speakers).
For an Electric Guitar track, you can view the Monitor pop-up menu by clicking Edit, and then clicking the back side of the amp. The Monitor pop-up menu appears with the input controls below the stage.
You should usually turn off monitoring when you are not playing or singing. When monitoring is turned on, your computer can pick up output from your speakers or monitors, causing unwanted feedback. Using headphones rather than speakers to listen to your projects can help eliminate feedback.
If you select your computer’s built-in microphone as the audio input, in the Audio/MIDI pane of GarageBand preferences, monitoring is turned off for all Electric Guitar tracks to avoid unwanted noise.

How come multiple audiotags in ebook can play all together in the last version of ibooks and ios6 while before they fade eachother when play key is pressed ?

in ipad1 with ios5.1.1 and latest ibooks app audiotags stop the last music played when the new music starts
in ipad3 with ios6 and latest ibooks let all the music play together with a resulting mess
in ipad2 with ios6 ibooks fade the last tag that is playing when the play key is pressed in the new audiotag

Gah. So It looks like the first version of the song on your iPod is the definitive version of a song (as is the case in iTunes). So in order to ensure that the version you want plays, you have to:
1. make that the only version in iTunes (or first in the file structure)
2. update Genius
3. sync your iPod
BOO. Too much work (I'm still going to do it though...)
I would really like a feature that allowed you to specify which song would be chosen (the existing rating system would seem to be easiest).
Another solution I thought of still requires a lot of work. This is assuming you prefer It would go something like this:
1. Create an directory structure at the root of your library that would prioritize tracks, such as:
a) Albums (for full length albums)
b) Collections (for best ofs etc.)
c) EPs (for singles or remix albums)
e) Live Performances
-assuming you prefer album versions over remixes over live versions, or more directly:
a) High Priority
b) Low Priority
2. Place Each Album or individual tracks in their appropriate folder.
3. Reset your iPod
4. Sync
The directory structure will intrinsically place higher priority versions on you iPod first, making them a priority version there. Pain in the...

USB device failed, when I plug in iPhone 4S running windows 7 (64bit)

When I plug in my 4s it says USB device failed. In details it says that windows terminated the process (error 43) I tried telling it to use the apple mobile device driver, but that errors as well. I last synced this phone in June, with no issues. I have uninstalled and re installed iTunes. I'm scratching my head now. Any help is appreciated

Thanks alot mate, Sloved my problem

Error message on ejecting USB device even when ejecting properly

I always click on the eject symbol in Finder before removing a usb device but I usually still get the message that the device was not removed correctly and damage may occur. I have also gotten the message when using Eject from the Menu. Anyone else have this issue? This has happened in 3 different OS versions, not just the new one.

You're writing of the Sidebar on a Finder window, right? If so then, yes, that should unmount the drive. But if you have your Finder preferences set up to display drives on your Desktop, try dragging the HD icon to the Trash. It may stall for a few seconds but the drive should be properly unmounted. If you still get the 'drive was not properly ejected...' errors, I don't know what to tell you....

No key event when compose keys are pressed

I am supporting a legacy application for Sabre which maps some of the keys differently. For example, on a French keyboard the Compose key which is used to put a ^ on top of the vowel characters is to be remapped to produce a special character called a "Change Character" that has a special use for reservation agents that use Sabre
The problem is, the first time you press the ^ compose key there is no key event apparently because the VM figures it doesn't yet know what key to report, it is expecting you to press a character such as 'o' and then you get an 'o' with a '^' on top of it.
If you press the ^ compose key a second time, you get the following key events:
keyPressed
keyTyped
keyTyped
keyReleased
On the screen you will see two ^ characters appear. Currently I remap the ^ character to the "Change Character", and I suppress the second keyTyped event so that I only get one character. The problem is that the user ends up having to press the key twice to get one "Change Character."
I have no fix for this problem because there is no key event produced when they press the ^ compose key the first time.
By the way, this behavior appears to have been introduced with jdk 1.3. The older jdk did produce a key event the first time you pressed the compose key. I would expect that this behavior was considered to be a bug and was fixed in jdk 1.3.
Is there some other way to detect when the user presses a compose key? If not, is it possible for future jdk releases to report a keyPressed event when a compose key is pressed? This event would not cause a character to appear on the screen, but would allow programs to detect when the compose key is pressed.
There is already a key on the French keyboard that behaves this way. It is the key to the left of the '1' key and it has the pipe symbol on it. If you press Shift plus this pipe key, no character is produces but a keyPressed event with a keycode of 222 is produced. I merely point this out to show that there is a way to report key events whithout producing output on the screen.
Thanks, Brian Bruderer

I don't know if this actually helps, but it seems that you can bind an Action to a dead key like the circumflex of the French keyboard
Keymap keymap = textPane.addKeymap("MyEmacsBindings", textPane.getKeymap());
Action action = getActionByName(DefaultEditorKit.beginAction );
KeyStroke key = KeyStroke.getKeyStroke(KeyEvent.VK_DEAD_CIRCUMFLEX);
keymap.addActionForKeyStroke(key, action);I saw this on a Swing tutorial and modified it slightly. Have a look at it :

JSlider -- catch when arrow keys are pressed

Hi,
With a JSlider, when it has focus and a user presses the left/right arrow keys ..the thumb on the slider is moved to a new value. I tried adding a keyListener but that didnt work...how can I catch when a left/right arrow key is pressed??

Screen shows when ALT key is pressed

Hi,
For some reason, photoshop CC has started showing a big ugly ALT next to my cursor when I press the ALT key. I dont want this! It gets in the way.
Im not sure how I turned it on, and would LOVE to know how to turn it off.
Many thanks!
G

OK found it.
The driver for the wacom tablet I use had stopped functioning. I think a derfault windows driver kicked in instead and was kindly telling me what keys I was pressing.
A simple reboot did the trick - it was NOT a photoshop setting.
Thanks anyhow.

Equium A210 hangs on Post when any key is pressed

Hi, I have a Equium A210-1C4 that has an odd error, when I boot the machine and don't touch the keyboard it loads into Windows fine and everything works as it should.
If the machine shuts down unexpectdley,on restart it shows the common selection of safe mode and so on with the countdown timer, if I try and select one of the other options with the arrow key the timer stops and the machine hangs (as soon as I press any key) I then have to power it off and allow it to boot without touching anything in order to get it working again.
The same thing occures if I try and press F8 on boot, it just hangs.
I can get into the BIOS settings and also select the boot order settings. The keyboard is functioning well within windows (no stuck keys) and I have reloaded the O/S and flashed the BIOS to try and resolve this.
The Laptop had Vista loaded origianlly but now is Win 7 - both O/S's have had the same issue
Any ideas would be great
Thanks

Since you traded keyboards and got the same results when booting into Windows, it sounds like a Windows issue. Running the Recovery disks would reimage the hard drive and probably fix the problem. However it would wipe out all of the programs, files and settings that you installed and set since you got the computer. It would fix the problem but could cost you a lot in time and preparation by having to backup all of your files, music and pictures. Plus you may need to let some of your program publishers know that you are doing a reimage so you can get your software reinstalled without having to pay a second time. Depending how much stuff you have to backup, this could be a very time consuming process to fix this one problem.

Code to call a function when enter key is pressed

hi all,
In a table control program i need to call a function when i press enter key...
but im not able to do that since the function is always called when i press a push button on the screen.... can any one help me in this.. please....

Hi John,
You are not getting any value in SY-UCOMM when you press "Enter",because the function code is not set for 'Enter" key in "Function Key" of the GUI-STATUS..
First define some fucntion code say 'ENT' for the Enter button available in "Fucntion key" of the GUI status.Once you done and activate the program and test it.The function code which u defined will be coming to SY-UCOMM field when you press 'ENTER" button and you can handle the various fucntionality whichevcer you want on "ENTER" .
Eg:
case sy-ucomm.
When 'ENT'.
Endcase.
