The app I have been helping on was vfp7, and worked fine on W7 and W10, but since upgrading the project to vfp9 the W10 just hangs - doesn't even load. The little blue circle just sits going round and round, and I eventually have to reboot. Nothing shows up in Task Manager either. I have run the Windows compatibility thing, and that said it changed a few things, but still no luck. It won't even run locally - if I put the whole thing on the W10 box, and try running it, I get the same results.

If anyone can shed any light...Thanks!
