Hey there SketchUcation, this is my first time in the Forum. I'm not sure if this is a Sketchup (SU) issue or an operating system issue, but recently when I'm trying to open a SU file, my computer tries to open another SU file from a completely different project folder at the same time. I'll see both SU files appear on my screen but neither will open completely to let me work on them. What's up with that?
