[GD-Windows] strange debugging problem

[Andras B. <and...@gm...>]

While my application is running, I can use alt-tab to switch to other  
programs and then switch back, and all this seems to work fine. However,  
when I switch to Visual Studio, and put a breakpoint in the source, while  
the program is running under the debugger, the program just.. well.. I  
don't know how to describe it, it kinda hangs, but it does this in a very  
strange way. The VS debugger says it's still running, but when I try to  
break into it (using the break all command that should just stop at the  
current instruction, wherever it is), it can't. The callstack window does  
not respond anymore, and I can not continue, or step anymore.. The only  
button on VS that works is the stop debugging. And it's funny, but when I  
say stop, I can actually see a couple more messages in the debug output  
window that my program is writing out..

Anyone experienced anything like this? Any ideas about what might cause  
it, and possible workarounds?

This is on VC++ 7.1 /Win32 XP


thx,
