bug in wxCreateHiddenWindow function

[Eran Ifrah]

Hi,

I found a bug in wxCreateHiddenWindow function.

I tried to call wxExecute from within a dll (does it matter?), however I am
getting an assertion
'failed to create hidden window for wxExecute'. Stepping into WX sources, I
found the bugged line:

at utils.cpp, line 1533 (in function wxCreateHiddenWindow()):

if ( !::RegisterClass(&wndclass)  )
{
    [...]
}

the above condition should be modified to:
if ( !::RegisterClass(&wndclass)  && GetLastError() !=3D
ERROR_CLASS_ALREADY_EXISTS )

I have tested it and with my fix, the code works properly (I am getting the
process termination event).

I am using wx2.8.4 distribution, on Windows XP sp2, Using VS7.1

Thanks,
