I just recently upgraded my sketchup to 2015.
I currently run a 64-bit version of Windows 7.
I did not have this problem when running sketchup 2014.
Whenever I try to access my Sketchup files .skp my entire windows will turn black for 1/2 a second. Close all programs without warning, or an error message, and just leave me back at my desktop, with nothing open.
This occurs only whenever I try to interact with the sketch-up file. I don’t even have to open it for my desktop to refresh.
Even my mouse hovering over the file for a split second will trigger this.
Because of this bug I am unable to make copies of my files, or even drag them somewhere else. Simply hovering or interacting with the folder which contains any sketch-up file will trigger the same thing.
I hope there is a fix for whatever bug this may be.
