Periodically, in Sketchup for Web (app.sketchup.com) the number keys 1,2,3,4 stop working. They still work in other Windows apps and programs, just Sketchup. Closing Sketchup and restarting fixes the problem. Cannot identify trigger for this bug
Please reassign this topic to the Technical Problems > SketchUp for Web category.
Your machine specs and IDs are not of much concern here, as SU4Web runs in a browser environment. What browser are you running it on?
