I have run into this problem before and don't recall the solution. When in layout mode, shift dragging and option dragging objects has ceased to behave properly. It's as if the shift and/or option keys aren't even depressed. The problem appears to be isolated to FileMaker Pro and does not affect other applications (e.g. Option dragging a file in the finder behaves correctly).
Has anyone else experienced this problem? Does anyone have a solution?
FileMaker Pro Advanced 11.0v4
OS X v10.7.3
