I have an assembly that is relatively small (I have many other assemblies with more parts and mates), but for some reason the file size continues to rise.  The file size is up to 100 mb and saving takes forever.  I have this assembly inserted into another assembly and that assembly file size is only 17 mb.  I am running SW 2010 SP 2.1 x64.  I have attached the assembly stats from assembly expert.  I have no idea what is causing the file size to balloon up so much.  Any help would be much appreciated.

thanks!
