I have this problem on a very repeatable basis. FMPA v12 and beyond. It kicks in when there are 30+ files open. Many of the text inputs slow to a crawl. By crawl we're talking about take a sip of coffee between typing a letter and having it draw on-screen.
It happens every time I open certain solutions.
Any updates on this issue? It seems to be still present in 13.
Thank you for your post.
This issue only occurs with Mac OS X after long period of time and many files open. Our Testing department verified the issue under FileMaker Pro 12 and FileMaker Pro 13.0v1. However, the notes for FileMaker Pro 13.0v2 shows this has been fixed. Are you running FileMaker Pro 13.0v1 or 13.0v2? If the latter and you are still having this issue, please let me know.
I just updated so my observation referred to the v1.
