Issue with Dropping stuff

Last few days I've noticed an issue with dropping stuff that I pick up.
Up to now, if my inventory is full... I just click on the ground and whatever I have in my hand drops.
However the last 48 hours I can't do that unless I attempt some action. "Thrust" for instance... that drops the item, but my toon doesn't complete the action... only drops whatever I'm holding.
Dropping from inventory works reliably.
1 in 10 attempts that I can pickup, see tool tip of item, and then drop it without putting it in inventory or attempting some other action.
