[AltGr] & [3] throws the IDE window away

[MyTrial]

I don't know if this is a problem of mine, maybe someone can help me. I use the PureBasic IDE with PureBasic 4.30 (x86) on a MS Windows XP. If I use the keys [AltGr] & [3] the IDE window is throw'n away. But PureBasic is always running, like seen in the taskmanager and in the process explorer. I found no way to get the IDE window back. The running PureBasic must be killed and new started. All defined parts (the editing sources) are deleted out of the IDE. I have searched in all boards but found nothing to that shortcut theme. Somebody knows that? And can help?

just tested, I happened to have the 4.30 still installed.
no problem here.
[alt gr] + [3] just inserts the "to the power of three" char properly, no effect on the windows.

Does it work with 4.40 instead of 4.30? You need to use the latest PureBasic if reporting bugs.

@Kaeru Gaman: Thanks for your response. By that it must be a problem on my machines. Thanks.

@UserOfPure: (1) I am programming applications for industry work and are not allowed to use fresh versions before they are defined as stable (from my boss). (2) I didn't report a bug. I have a problem and don't know if that is from my machines or is a short key from PureBasic. Therefor I asked. Sorry if that wasn't understandable.
