Screen will not scroll

Although Screen is set as "scrollable" in design, the emulator  will not scroll down, even if info spills over past the screen dimensions. 

I tried to scroll with Mouse, and also tried to scroll with the TAB key. It will not scroll, no matter what. Any ideas ?

Make sure whatever you want to scroll to is actually Showing!  If it's set to invisible, the screen will only scroll to the last thing visible on the page, and if what's visible doesn't fill MORE than the size of the screen, it won't scroll... why would it?

Check to make sure you have something that the screen can scroll to!
