Thanks for posting!
I was able to reproduce the behavior you've described and can confirm that this is specific to FileMaker Pro 11 on OS X. It also appears to occur when the zoom is set to 75%. I went ahead forwarded your post to our Development and Quality Assurance (testing) departments for further investigation.
Seems like a variation of the bug reported in these links:
Thanks you SO much TSBear! You all are on it like usual...I guess I should have said something earlier. I just kept thinking that the next update would eventually fix it. Sure appreciate all you FM and Mac engineers!!!
Yes...sounds very similar PhilModJunk. I've always been blessed with 20/20...so I had not noticed the problem, till I finally heard one of the new gals cry in frustration. Turns out everyone is blind in the office w/their 150% settings. ;-)
Now that I've thoroughly tested it...it is really consistent as described (I kinda only wrote the short version of all my testing...takes to long to type). Man how time flies...not to sound like a professional wrestler at all, but I used to work for Apple (16 years ago now) as a Retail Sales Manager and Level 3 Tech...so if anyone has any questions I could talk tech or specific beta testing methods that I used once I got on it. Just sometimes it's nice to know that a person is not talking to a total non-propeller head. ;-)
Those links came from my known bugs list database so I was checking to make sure a new entry wasn't needed. In addition to being a downloadable database file, I also use it to maintain a pair of Known Bugs Links here in the Report an Issue section of the forum:
