Unconcious / mouse cursor dissapears.
 

Have had this happen several times. Its a little odd, and very annoying.

When i go unconcious and then get back up - my mouse counter stays invisible.

I can type, and the mouse can also be moved around and used. (evident by the fact that i can highlight buttons etc with it) - i can't see the actualy mouse arrow though.

It happens every single time i go unconcious and usually forces a relog, i have one one instance stayed on, and after a good while it came back to visible. However, i dont go unconcious enough and in safe enough areas to see if its a consistent event :)

Moved to technical discussion.

We have no control over client issues.

try to press F12 twice to disable / enable mouse control .. maybe it makes your cursor reappear

This also happens to me every time I get purple'd. I just click both left and right at the same time and it usually fixes. never had to log out from this before though. Though i cant imagine you haven't tried this... but thought Id throw it out there in case.
