One of our users reported this problem after upgrading to FM13 from FM12 on a Windows 7 PC. We went online to the user and found that when switched to another Windows user account the problem was not evident. In other words, it appeared to follow the Windows user. I called FM Support and they have no other similar issues reported. They also pointed out that the FileMaker program has no control over cursor behaviour or appearance. Will continue to investigate at user level.
