There is a user that has a FileMaker window open and a Word document open. If she clicks the minimize window on the Word document, her FileMaker window in the background goes to 0,0. I can't duplicate the problem on my machine. The only difference between our setups is that she is running OS X Yosemite, 10.10.5.
Any ideas what I could change in FileMaker to avoid this? I checked the layout to make sure there was no script trigger causing a window adjust.
