>>>I have 2 timers on a page that display 2 bmp's, 1 then the other repetitively for an alternating effect. I use an @ row,col say mybmp.bmp but when the form gets hidden, an error message comes up saying row or col position is off the screen. Is there a way to prevent this?

Timer.Enabled=.F.
BTW, it's much better to use Image control with Picture property alternated by Timer.
