When in metacard a stacks pixmapID < > its windowid then Dar's handler is working as a charm (here at least)
From the TD on alwaysBuffer:
"You can find out whether a stack is currently being buffered by comparing its pixmapID property to its windowID property: if these two properties are not the same, the stack is buffered."
From the imag007 tip at www.sonsothunder.com:
-- The next two lines force the current card image into the offscreen buffer
set the alwaysBuffer of stack pStackPath to false
set the alwaysBuffer of stack pStackPath to true
(My function only works on "this stack", so this does not apply. Maybe.)
Maybe a good test to add to my function and to the imag007 tip is a check on the pixMapID and windowMapID. If they are the same generate an error and don't set the imagePixmapID.
(If a stack is not in memory, I don't know if setting the alwaysBuffer does what we want. I haven't looked at that.)
