I have a situation where when working in a SolidWorks drawing it will suddenly just stop accepting input. The mouse works. You can move it around the screen but when you click on a toolbar or a pull down menu nothing happens. I restart SolidWorks and everything works fine a while but eventually it happens again. The problem only starts when I am working in a drawing, never in a part or assembly model. However, once the problem happens in a drawing, parts and assemblies stop working as well.

My system has been working fine for years. This just showed up a month ago. It started happening on my old computer running SolidWorks 2024 SP5 on Windows 10. My computer was 8 years old and scheduled to be replaced. So, two weeks ago I got a new computer still running SolidWorks 2024 SP5 but on Windows 11. Same issue. So, after years of no problems at all, now I can't get SolidWorks drawings to work consistently on my old or new computer.

Our IT department and our VAR neither one have a clue what the issue is.

Any help would be greatly appreciated.
