wine users - Mar 2001 - wineserver: write_request: Assertion `thread->pass_fd == -1' failed.

Hello all,

I'm new to Wine and am getting the following error when I try and run my
program,
any ideas on what might be wrong (is this a bug in WINE)?

wineserver: request.c:235: write_request: Assertion `thread->pass_fd =-1'
failed.

Thaks in advance,
Tushar.
