>Is there some way of getting VFP to update the source. I have a .prg that shows "Source is out of date" in the debugger. The file has been recompiled. The .fxp file is up to date. There are no other copies of the file on disk. I've even exited VFP. But it insists on running the old code. This is happening much more frequently than it used to. (VFP 8 SP1 on XP Pro). I'm even beginning to suspect the OS!

Are you sure it's showing this error for itself? Or is from something this program is calling? i get that every now and then

at any rate, erase the fxp file and run the prg.

i've got to where i erase all fxp's in my working directory tree periodically out of a habit i picked up using vfp3 beta :)
