pq07365.txt  STACK OVERFLOW WHEN LOADING VISUAL PARTS FROM V2 to V4

A walkback is generated when parts that were created in Version 2 (and not changed 
in V3) then loaded in VA Version 4 when you try to open the composition editor on a 
part.  The walkback is a stack overflow that is generated when Dictionary>>
#mutateObjects:fromPlatform:named:withDefinition: is mutating an association set.

Workaround: Load the application in version 3 first, resave the parts, version and release.  
The updated application can then be inported and loaded into Version 4.
