[comp.sys.amiga.tech] screen flipping bug

lshaw@walt.cc.utexas.edu (logan shaw) (07/24/90)

There seems to be a bug in 1.3 that I've just encountered.  I don't know
if other people have found this, or what, but if you know how to help, it
would be appreciated.

Description:
  Have two interlace screens open.
  Open another.
  flip screens using either Amiga-M or gadget and -BOOM-
  you are flipped back to a non-interlace version of your workbench
  screen, and from then on, things start to die very quickly.  Once, 
  I recovered.  Usually, it completely locks up.
  
Does anybody know why this happens?  It seems to be avoidable if I move the
most recently opened screen up and down a little before flipping it to the
back.  My guess is a screwed up pointer somewhere.
