I’m in the 30 day free trial of 2020 SU Pro. I just realized that the Select tool, although it works ok in the click to select and at least somewhat in the click and drag across entities to select, it definitely does not work click and hold and drag to create a window to select. Can anyone tell me why that could be?
Typically what you describe is due to the graphics card or its drivers.
Make sure the graphics drivers are up to date–check directly with the manufacturer, don’t trust Windows to tell you if it’s up to date.
Make sure that you installed SketchUp correctly by right clicking on the installer and selecting Run as administrator.
In SketchUp, go to Window>Preferences>OpenGL and experiment with the state of the tick box for Use Fast Feedback.
This could be the problem. Don’t remember doing either . I’ll try reinstalling.
OpenGL was the solution. Tried everything else because I had never heard of OpenGL nor had i noticed your “in SketchUp”. no luck. Finally dawned on me what you meant by “Windows>Preferences>OpenGL” meant. Changed "multisampling anti-aliasing to 0x voila! works as it is supposed to. Thank you DaveR!!
