problem: Character Development & Alternate Advancements

[Ken1985]

I can't move the slider in the bar to convert experience into AA, neither can I change the percentage next to it. Everytime I want to click it, the complete box moves as to relocate ...
If I lock the window then nothing happens when I click on one of them ...
I tried to change my windows settings, but nothing helps
All the tree's to invest the aa points are working fine

I have this problem with all my characters.

I have done all updates (game and profit ui)
