Haven't hit this particular strangeness *s* but when the debugger gets weird on me, I just pick Reset to Default on the Window menu (of the Debugger!).

HTH

> I used to debug under NT 4.x with VFP 5.0a debugger. Suddenly when debugger window came up today, all the buttons are disabled. Mainly the start debug(Forward arrow like button) button is disabled. I tried all possible things like booting up the machine, trying to use debugger with a different project. But no difference.
