has anyone had problems with 2009 going slow paning, zooming or regening while working inside viewports? if so is there a way to fix this?

have you allready tried to purge the drawing? and whats the detail level you use in the viewport?

i figured out the problem...the problem goes away when I change the Layer Palette to the classic layer manager, by setting LAYERDLGMODE to 0.  thanks for the help.
