SU 2015 - can't print or export 2D graphic

Running SketchUpPro 2015 (15.0.9349) on a MacBook Pro (OS X Yosemite 10.0). When I click on File/Print SU2015 hangs up and I’m stuck with Force Quitting. Same when I choose File/Export 2D Graphic. I tried the Forum trick of going into system preferences and trashing several files (such as com.sketchup.SketchUp.2015.plist), emptying the trash and then relaunching SU2015 – to no avail.

Never mind – now (for a reason unknown to me) I can do both. Sorry to trouble you…
