The forum

I did a search on this and say only a few unanswered itels from over a yar ago.

I installed the game and everything seems to run fine.  However, anfter i have been running for some time the mouse surser disappears!  I know it's still there and just invisible because I can move my mouse around and light up various opjects.

Anyone know how to resolve this?  It WAS working perfectly BEFORE the upgrade from Kubuntu 14.10 to Kubuntu 15.04.
