An update was released in July which _probably_ fixed this: [TalesOfMI.net article][1]

It's not explicitly mentioned as the acid pit bug but they mention addressing certain 'cursor issues'. Some of the comments on that page indicate that it was indeed fixed with this patch.

If you happen to test it and can confirm either way, let me know and I'll update this answer.
