>Yeah, you were right, it is in FPW 2.6. However, we have rebuilt the EXE and we don't call any APPs outside the EXE. I'm not sure if the networks are busy when this occurs, because it occurs at the customer's sites (though I'll start asking). Maybe it relates to the .MSK files in some way?

NT4 server on Win95 workstations (about 60 different PCs). Haven't seen the problem since building all .bmp and .msk into the projects. The NT server has undergone the usual number of fixes over time so can't tell if any of the SPs affected the problem.
