So you've updated to the latest version, and you're still seeing the error message?

Please provide the following information:

• The tweaker version, you can see it in the about box.
• The version of the explorer file. You can see it by opening the C:\Windows folder, right-clicking on the explorer.exe file, choosing Properties, Details, under File Version.
• The exact text on the error message that you're getting.

The latest non-beta version is 5.9.1. The latest beta version is 5.9.1.4. You don't need the beta version if you aren't using an insider build of Windows 10, but you can use it as well.

What version are you running now? You can check that in the about box.

Please make sure that you're using the latest version of the tweaker. If not, let me know whether updating to the latest version fixes the issue.

It should already be supported. One known limitation is that if the taskbar is set to auto-hide, the width is not restored.

Should be fixed in v5.9.1.3 beta.

Should be fixed in v5.9.1.3 beta.

Please try the newly released v5.9.1.3 beta. I believe that the issue is now fixed. It took some time, but better late than never :)

The tweaker doesn't do anything related to auto refresh, so I hardly believe the issue is caused by the tweaker.

I'd be glad to look at it fix it, but unfortunately, without a way to reproduce the issue there's not much that I can do. I assume that a computer restart (or maybe an additional restart of explorer) will fix the issue. You mentioned that you're using other customization programs, so perhaps there's a conflict with one of them.

If you find a way to reproduce it, please provide the reproduction steps.
