Can anyone help, if not this is just a bug report.

When I click any ability that opens a pop up window for instance the druid shape shift or if I have a level 1 and 2 ability so it opens that small window to ask which one I wanna use the window will not close, not matter what I do it just won't close until I shut the game down.

I can't figure out how to force it to close or what could be the issue.

Thanks if anyone knows what could solve it for me.
