No guarantees. While I have Mavericks, I don't use CS5.5. It opens, but that's all I know.
It was not one of the versions tested (or slated to be fixed by Adobe). Only CS6 and CC.
I have freshly installed Mountain Lion and CS 5.5 and the problem is still occuring. How's that possible, I have no idea, but it obviously isn't a Mavericks issue.
I am also experiencing similar weirdness in Illustrator and Acrobat.
If anyone has any theories, I'd love to hear them.
UPDATE: Just discovered the issue: RightZoom.
I'm glad you reported it. Love those handy third party utilities. Hate those pesky third party utilities....
