As of today (11 December 2012), I have removed QuickCursor from sale
in the Mac App Store. This means that the app's binary is still in the
App Store (you should be able to re-download it if you purchased it),
but no new purchases can be made.
Due to an increasing number of problems with OS X sandboxing,
QuickCursor doesn't always work as it should with the apps it's
supposed to be compatible with, and inconsistently for many. What
works for one person doesn't for another, and it's not clear why.
If you recently purchased a copy of QuickCursor, please contact the
Mac App Store's support team about a refund. You deserve a working app
without a whole lot of workarounds, and I'm not confident we can find
a solution that will get approved in the App Store at this point.
I'm sorry about this, and I apologize for not being able to deliver an
update to fix all the running issues within a reasonable amount of
time.
