Unable to mouse click anything in game

[Sororf]

I just downloaded the titanium client and when I launch the program with the launch titanium file it launches in full screen and I believe when I used to play here it was a window. Anyways I cant click on anything, I have to tab and hit enter to even get logged on, once I am logged in I cant click on a server to select one so I am stuck at that point.

Has anyone had this issue or know a way to fix this? Thanks
