Return of Reckoning

I have an issue when I go in scenarios my left click just doesn't work so I can't click on the players and my spells and the only way for me to leave the scenario is to alt f4. I'm pretty sure it's a bug but I wanted to know if any of you knew a way to stop this. I sent a bug report on the bug tracker, but after 3 days I have no answer and the bug is still here

same problem here since i restart a few weeks before. yery annoying to hit /reload ui all time long.
