Thanks for the info. I did not know how to read the tree and I got shocked 
when I saw that _beginthread and friends were called from both runtime 
libraries.

In order to minimize the sources of error I have downgraded to python 2.3 
and compiled all my extensions with MinGW. At least in that way I have got 
one of the random crashes reproducible and have been able to fix it (four 
characters missing in one line of an xpm pixmap).

Thanks again,

Armando
