IMHO the best thing to do would be to use a (generic) wxAssertDialog 
that would use wxCollapsiblePane and the stacktrace would be 
initially hidden. For me, the most annoying thing about the 
wxStackFrame performance is that when an assert happens, the app 
completely freezes and it takes many seconds for something to happen. 
In the meantime, you're given no indication that it's an assert 
showing up. And when the assert finally shows, I usually don't need 
the stack trace to fix it anyway.

So if the stack trace was initially hidden, a) the assert dialog would 
show up instantly and b) wxStackFrame would be only used if the user 
clicked on "Details". This alone would make the performance of 
wxStackFrame much less critical.

It would also have the benefit that we could use well-labeled buttons 
like "Stop", "Ignore" and "Ignore All" in the assert dialog -- maybe 
it's just me, but I still find the mapping of standard Yes/No/Cancel 
buttons to Stop/Ignore/IgnoreAll actions very confusing, even after 
seeing the dialog for years.

Regards,
Vaclav
