Move Part w/Physical Dynamics allowing Parts to pull through.  Isn't it supposed to treat any Part features as 100% hard solid?   I'm running Intel i5 2.40Ghz w/8 Gigs of Ram  on Acer Aspire 5 "gaming laptop" (was about $700 two years ago, same exact currently sell on Amazon for about $780).  Is that enough or is that my problem?

Anyway to tell SW to 'just take your time' and stop if need be to allow parts
