Miscellaneous: Hansl Bigroon's dropped list locked up my UI.

Try replacing the default UI with the one in my sig and see if it fixes it.

This is a Titanium Client issue, IIRC (not a P99 issue). Fairly sure there are other bug posts about spamclicking.

This happens to be me all the time when a quickly spam-click on a bag on the ground.

The fix is to relog (the item will reappear on your cursor upon next login).
