I brought Close Combat 2 and the odd time it crashed, when i return to desktop i cannot click on anything in the GOG Galaxy, i have to force close it and restart in order to do so. Not sure if this is a common issue or unique to CC2. It could be an issue with my pc because ive notice it happening on Steam lately too which was never an issue before.

Did you try running the game without Galaxy running? Close Galaxy (make sure it's not running in the tray), then go into the game install folder and look for the game's .exe (if there's a launcher, don't use that, use the .exe) If the game still crashed and freezes up your cursor, then it's something to do with the game or your system.

Since it's happening with Steam as well (I assume with different games), I'd lean towards it not being a Galaxy or Steam issue. Likely something on your PC.

Haven't tried that yet. But i closed down CC2 (no crash) and it seems GOG Galaxy is there but not there to the PC, like if i click on top bar of GOG i actually click on a shortcut on desktop.

But yeah will try running CC2 from its own launcher and will try running a different game. Just wondered if others have had this issue.
