I also noticed that diabled keywords in other adgroups get activated from time to time (to see if they are doinbg any better?).
Anyone seen this?
This is too weird for me.

This is a classic 'corner-case'.
Sometimes a disabled keyword (that has not been deleted) will show up for a few impressions after a change is made to the ad in that Ad Group.
This doesn't happen often, and doesn't happen for long - just for a few impressions. Then it reverts to it's true status, which is 'disabled'.
Best to just delete the keyword, then re-use it in a more targeted Ad Group, IMO.
