@TheGuz while the open and save issues are now resolved, one user still has performance issues unfortunately. Whenever they click, drag or do something in Sketchup they have a 5-10 period of a freezing Sketchup with “Not Responding” added to the title screen. If they click again when this happens then it freezes completely and they have to close the program.
I’ve tried the new Sketchup 2019 and install an updated graphics card driver, but no breaktrough yet. I’ve also checked for the Materials panel especially, but it doesn’t matter in this case if this panel is closed.
I hope that you have a magic solution for this issue as well?
