I know, there are many topic concerning this problem, but i ask myself this question since YEARS.
When i read all the stuff written about that problem, i looks to me, that Trimble does not really know what or why this is happening, right?
I use SketchUp since Version 6 and use it a lot for my work - i have planned and visualized around 150 stores (in combination with several rendering plugins, Thea Render at the moment) with SketchUp and i know the problem since a very long time - and it got worse over the years. In my opinion it has nothing to do with the Windows Version I am running it on, or where i save the files. It crashes in all variations and totally randomly sometimes when saving.
So my question to Trimble is: Why are you not able to fix that? Other software that i use since decades (Photoshop) never crashes on saving, ain´t that funny? Or other software that uses OpenGL …
I hope i get an anwser …
PS: Yes, i got my Windows always up-to-date, as well as the Nvidia Drivers.
