VC6 debugger hangs wxVidget app if breakpoint in event handler?

[Carsten A. Arnholm]

Hello,

I have been experimenting with writing apps with wxWidgets 2.8.2 on Windows 
XP and Linux/Kubuntu for a while. My development is on Windows at the 
moment, using VC++ 6.0, as this is a well known development environment for 
me. I have been using it for other C++ development and debugging for years.

I have been experimenting to find ways of designing wxWidgets GUI with some 
success, but also with some problems. I have tried DialogBlocks and although 
it has many very nice features and I am able to generate some code that 
works, I feel my hands are a bit tied there. I have also tried designing GUI 
using wxGlade and that is a nice tool. At the moment I set up the overall 
projects with DialogBlocks, design and generate the C++ code with wxGlade 
and combine the output from the two in Developer Studio, for compilation and 
linking/debugging. This way I have made programs that work ok, essentially a 
wxFrame with a splitterwindow, some menus etc. The event handlers work also.

What is a bit of a puzzle is that if I try to debug and set a VC++ debugger 
breakpoint in a event handler of my wxWidgets programs, then everything 
freezes. And I mean *everything*. Even the Windows Task Manager is very hard 
to get to to stop the program, and usually the only way out is to hold in 
the power button on the PC and force a "hard stop" and reboot. Not so nice.

Any clues to why this is happening? Is it a known problem? The program as 
such seems ok, as it runs under windows (without debugger) and under 
Linux/Kubuntu using KDevelop/GCC.

Advice or suggestions appreciated!
