I've remapped my right arrow key to attack (so I can hold it down with my thumb while using the keypad for movement) but I have an odd issue with it.

If I ever click on one of my hotbars (say, drink a potion), then the right arrow key will turn into a "turn right" key. It won't turn back into an attack key unless I click on any non-hotbar (or other UI area such as the chat window) part of the DDO screen. Basically, I need to click on nothing to return the key to what I want it to be.

Has anyone heard of anything like that? Is there any way to fix it?
