>My foxuser file after all these years is 27meg large. Any downside to just deleting it? I notice for a week now that VFP takes a long time to boot up.

It'll lost stuff like your command window size and position, and toolbars, ect.
All of the real important stuff is stored int eh registry, so, just move your FoxUser instead of deleteing that, then, if you get something you didn't want, just move it back.
