OUTSHOW=OFF setting in config.fpw in vfp installiation directory fixed this problem.

Thank You!

>I know that SHIFT+CTRL+ALT hide all windows. It can be disabled by putting OUTSHOW=OFF into the CONFIG.FPW. I don't see such effect with ALT+SHIFT on my PC, though.

But when I need "#" character, I have either switch to English keyboard or press {right ALT} + SHIFT + 3 simultaneously. When I press {right ALT} and SHIFT everything (except menu) dissapears, if I press button "3" with {right ALT} and SHIFT then all windows appears for a second, then (if I am still holding alt+shift) everything dissapears again.
