Dear collegues,

I encountered a problem on the computers of one of our clients. Every time
our .EXE tries to
call an external .DLL the error shown below occurs. The same .exe works
without problems on
other computers. The client uses WinXP on his computers, I think the problem
lies in some OS
setting. Has anyone seen something like this before ?

Kind regards,
Jan Groenestein

Try to run your app within "Dependency Walker".  Look at the log window
after you get the IDSC.  I'm pretty sure you will get more details
there.  Something like loading User32.dll from the temp folder instead
of system32 (pretty usual for virus infected computer!).
