How to stop screen "flicker"

[Mark Schonewille]

Hi Dave,

It is not clear to me what you are trying to accomplish. Why do 
you set the visible of the stack to true or false if you're 
going to close it anyway?

If the problem is that the stack flashes *before* its visible 
property is set, it is possibe that removing "as toplevel" from 
your script solves the problem. Why did you include that?

Completely contrary to HyperCard, Revolution's "lock screen" 
command prevents windows from being redrawn but does not prevent 
them from appearing on screen. You might want to set the loc of 
the stack off-screen before changing the visible property, then 
hide the stack and set the loc to the original value.

Best,

Mark
