Hello.

I took a look at this.

After rebuilding MESS with allot of debug and prints i suddenly realized that
MESS was also crashing at the very same spot (in a timer callback function).

The odd thing was that no unhandled-exception was thrown like in Wine. First i
thought it was an exception handler cleverly installed. But no.

It seemed that Windows was hiding this exception. Then i found this:

http://www.experts-exchange.com/Programming/Languages/CPP/Q_22041925.html

Which is the same. So i think that windows for some reason protects timer
callbacks (from WM_TIMER) with a TRY/CATCH or similar. Very annoying.

I will construct some tests and a fix.

Thanks,

/pedro
