Pywin32 treats handles as signed longs. There appears to be a difference in how 2.4 and 2.5 handle them: 2.4: >>> struct.pack('l',-4100000) '`p\xc1\xff' >>> struct.pack('L',-4100000) '`p\xc1\xff' 2.5: >>> struct.pack('l',-4100000) '`p\xc1\xff' >>> struct.pack('L',-4100000) __main__:1: DeprecationWarning: 'L' format requires 0 <= number <= 4294967295 '\x00\x00\x00\x00' Try changing the sruct.pack format to lower case l's, and if that solves your problem I'll change it in CVS.

I changed to lower case l's and that seems to have done the job. Thanks!
