I saw this in the first buld of version 12 on Windows 7, now it's back with version 13: When I open the inspector to change the properties of an object on the layout (say, an oval or rectangle), then apply a gradiant fill and select starting and ending colors, the pops up stay on the screen -- one for every time i clicked. And I mean they really stay. I can't get rid of them by changing layouts. If I minimize the application window, the sold background of the popup windows are still there on my desktop. If I open another application, it appears to open underneath them.The only way to kill them is to close FileMaker.
