The VFP app needs to be running side-by-side with the medical software on the same machine for reasons that are too esoteric to bore you with. However, the VFP app is also installed on about 100 more typical PC's at our location, and it never exhibits this behavior.

>Should you back up and take the VFP application off this machine? Sounds to me like this machine was supposed to be dedicated to the medical software. Maybe instead of trying to figure all this out, you should just go get a box and put it in there to run your app.

>>We have an NT4/SP6 box running a proprietary medical software application side-by-side with our VFP application. The medical software does some impudent things, like apparently hooking messages to other applications so that whenever they minimize or otherwise yield foreground, it asserts itself to foregroud and re-maximizes to basically function in kiosk-mode (i.e., you then have to hit alt-tab or alt-esc to do anything else on the system).

>>The _weird_ thing is that sometimes when you do a mouseover on the VFP app (when it has been brought to foreground with alt-tab, for example), the system will start throwing up "Unable to locate DLL" messages (this appears to be a sysmodal messagebox). It always says it cannot find jvm.dll. Once it starts doing that, you're sunk... i.e., it then happens with every subsequent mouseover event occuring with the VFP app until you exit the medical application software and restart it, then things work fine.
