When I hold down the shift key to queue up movements the game seems to hiccup for a moment and then not let me queue the movement. The mouse continues to moves around the screen but the line indicating the direction of travel pauses as does the craft I'm directing. When the game does catch up the movement is treated like a single action and not a queued action (thus removing the previous step).
Just to make sure I'm not going crazy: THIS IS A TEST OF HOLDING THE SHIFT KEY DOWN WHILE TYPING, which appears to work.
What kind of information do you need from me in order to help diagnose/troubleshoot?
