Editing Rights Disabled?

My partner and I granted each other editing rights to anything each of us own. But lately, I've noticed when I try to open an edit window on one of my partner's objects, the edit parameters keep blanking out when I try to click on anything, either on the object arrows or anything in the edit window. Essentially, I've lost the ability to edit my partner's objects.

Is this something that got messed up in the newest release?

Edit:

Oh.. it turns out the problem was due to a setting in the Tools Menu called 'Select Only My Objects'. I don't remember setting that - perhaps it became a default in the new release. Anyway, unselecting that solved the problem!

Thanx goes to Lex Neva for pointing this out to me.

Thank you Lex--this seems to be a recurring reported confusion lately for some reason; I got some emails about this the other day too. Glad things are well now, Sashi.
