Pack and Go Check boxes not working

When everI wanted to great a new assembly based off an oldassembly, I simply did a "save as" and edited my reference, butsince I got 2008 I have to use "pack and go" wich worked just fineuntil I upgraded from .01 to 3.1.

Basically I am unable to uncheck all boxes, I can't even use the"select/relace" function and use it to uncheck/check by name, Ican't even click in the "name" box on the main "pack and go"screen. But the search/replace name function still works (thankGod)

My work around is to go through my assembly and manually uncheckall the items I don't want to copy over, then use find/replace tochange out my part numbers. This is somewhat annoying to me andjust one more thing to take up time in my day.

Anyone else having this problem?SolidworksUser Interface
