Clicking In Character Select Screen crashes back to desktop and runs eq windowed

[Taiden]

When in the character select screen pressing Enter world for example dumps me back to desktop and puts eq into a windowed mode. Going back into the window and pressing alt-enter gets me back into full screen but as soon as I press enter world it happens again. This also happened during character creation when trying to spend skill points. The only way out is to end task, set resolution lower and then load eq again.

The issue seems to be resolution related. If i go back to one of the lower resolutions I can then get into the game, 1280x1024 seems to work.
The resolution I have set is 1920x1080 which if I can manage to get into the game runs just fine.
