Bug with the MMB pop-up window in Rhino 8

I just found that there is a bug in my Rhino 8 Evaluation when I set holding the middle mouse button to open the “Recently used” toolbar. initially it worked fine, but after activating it several times consequently, Rhino 8 warned me that there is no such toolbar. Then I checked in the list of toolbars and it really disappeared! What could be the cause of that bug?

Edit: I figured out that “Recently used” was somehow auto-renamed by Rhino 8 to “default.Recently used”.

that’s odd. What is listed under Options > Toolbars at your end?

This:

I wonder if that happens too when you disable any third party plugins.
Can you run _Reset, use “save settings for support” and send that file?

Sure, here are the settings. Rhino 8 actually crashed when I tried to export the settings initially. the export was successful on the second run. I also sent that file through the crash report window.

RhinoSettingsForSupport.zip (2.6 MB)

thanks, can you also run _SystemInfo and post back the results?

Yes, here is my system information. I just disabled the StereoView.rhp “StereoView” plug-in, because I don’t need it.
