Keyboard Issues with Character Movement - Mac Client

Running the game on my iMac with the Apple Keyboard. I have no issues with playing the PC version on Bootcamp, but on the Mac side, my character stops moving the moment I jump or tab to select enemies or NPCs. I have to release the key I'm using to move my character (in either direction), and press the key again to resume moving.

I don't know if it's a setting issue, however I've looked through the menus and cannot find anything that could be causing this.

Bumping.

Still have the same issue. It turns out it's any key I select while moving (especially tabbing through enemies) that will lock my character in place forcing me to have to depress my movement key, and press it again to begin moving.

I've tried two different keyboards, and still have the same issue.
