Strange drop down Menu In Layout

@lynewagner, can you post an image of the menu. Also, from your profile it seems like you are using Windows 10.

Please note, SketchUp is currently unsupported on Windows 10. Please see Early Adopters (of New OS Versions) Be Cautious for additional details.

PS- We plan to support Windows 10 with SketchUp 2016, which is scheduled to be released shortly
