SCS, you are the first person to weigh in with Solidworks. Cool, how do you like it? Do you have Hypermill experience or just starting? Welcome to our forums!
I suspect this is an Inventor only issue that is aggravated by also using Hypermill in Inventor.
Blowby, guess what? The escape key button on my SpaceBall only works if I click in the drawing window first! LOL
