ion3ds-20061020 not playing well with variable resolutions

[Geoffrey Alan Washburn]

	Hi, I've just started using ion3ds-20061020 and unlike prior versions, 
it seems to be storing the size of the display somewhere in my session 
information.  As a result when I connect my laptop to an external 
monitor all my workspaces are 1024x768 rather than 1280x1024.  If I 
delete my current session to resolve the problem, when I switch back to 
using my laptop's display the session remains at 1280x1024.  Is there 
anything more automated that I can do to reconfigure ion3 when the 
display resolution changes?
