Have you tried another mouse?
I don't know if you're still following your several month-old topic, but if so, did you ever resolve this? I just upgraded from Snow Leopard to Mountain Lion, and Indesign CS6 now has a flickering cursor that makes it very hard to use. I've gathered from other posts that there may be something specific about upgrading from Snow Leopard to Mountain Lion, and it may not be a coincidence that on my laptop, where I upgraded from Lion to Mountain Lion, Indesign CS6 works fine!
This is driving me crazy! Did you ever fix it?
Upgrading the OS rather than doing a clean install of the new OS version and reinstalling the applications is a gamble. Sometimes it works fine, sometimes it doesn't. It's possible that's the problem. If you didn't reinstall ID after the upgrade, you might try that.
I've seen some people with what may or may not be similar problems saying that deleting the InDesign preferences, cache, and pretty much everything in "Application Support" for Indesign fixed the problem. Is there any risk in deleting those things?
As long as you have your custom presets backed up, there is no harm deleting the InDesign preferences and the InDesign recovery folder.
MANY thanks to both of you for very helpful replies!
Weirdest thing (but nice): yesterday the cursor in InDesign was flickering so badly I could hardly tell where it was, much less which type of cursor it was, but today it seems to be fine! I am unaware of anything I did that might account for the change. I rebooted, but I'd done that a couple of times before since upgrading to Mountain Lion, just in case, so I don't know why it's working, now, or whether it'll go back again to flickering. But I'm hoping for the best. I'm keeping your suggestions saved in case it recurs.
There have been many reports of problems using Apple wireless mice.
You can Google this issue.
Some attempts at a fix:
- Adjust scrolling speed in Preferences
- Clear battery contacts
- Optical sensor is dirty
If you have a old wired mouse that still works OK, try using this to test the problem.
