moving the cursor around the screen will often see it disappear and reappear somewhere completely different onscreen.

ie. youll be moving towards the bottom right of the screen and suddenly its over on the left side. or in the middle, or top left... its annoying

does it in the ingame menu screens aswell

nevermind this is a known problem with older builds of scummvm

for anyone with a similar problem in the future -
the version of scummvm included with this game at time of writing is the problem. youll need to download a newer stable release from the scummvm website.

wish gog would keep emulated games (dosbox, scummvm etc) up-to-date with the latest builds. its a nightmare having to go through on a game-by-game basis updating them manually.
