In place mates????? Why are they not locking components in place?

I swear my Solidworks has went AWOL. I have been having weird issues this week. First its opening multiple sessions from Windows Explorer, then I lost the pack and Go/ rename shell in Windows Explorer. Now Im building assembly I guess top down from a existing part, when I build around it the sketch is on a place and fully defined but I can drag the components with the mouse? What it is going on?!
