Weight Map Editing in 4.7.0.12 won't erase nor smooth (fixed)

ghastlycomic

I'm trying to erase some weight maps and smooth them but the Control and Alt keys don't seem to work anymore when painting weightmaps.

Have these keys been changed to something else?

Okay. Turns out it was one of those "shut down the software and reboot it and see if it works now" kind of bugs. Everything working after a reboot.
