Not sure how else to describe this issue.
Select a unit/stack and set a long move path Click the Move button and it moves normally. Click the move button a second time while the stack is in the middle of moving and the movement speeds up (what I call fast movement). This is a nice feature to speed movement of stacks.
However after doing this fast movement, the user interface is hung. By that I mean I can no longer select units/stacks. I can use the 'next unit' button to select but the direct cursor on a unit select no longer works. You have to exit the browser and restart to fix it. This is very annoying.
