MBUtton Up routine causing non-Live middle mouse button issues

[spice3d]

Describe the bug
If I click the middle mouse button in, say, the Google Chrome browser, I get two clicks instead of one. This also causes middle mouse button issues in Ultimate Midi Plugin's VST UChord. Fortunately, not a lot of programs uses a middle mouse click.

To Reproduce
Steps to reproduce the behavior:

1. Open Google Chrome
2. Click on a bookmark favorite with the middle mouse button. This is the same as Ctrl + Click with left mouse button which opens the bookmark in a new tab.
3. The bookmark will be open in two identical tabs.

Expected behavior
Only one tab should open in a new tab.

Screenshots
N/A

Desktop (please complete the following information):

• OS: Windows 10

Additional context
Setting middleclicktopan to 0 in the settings.ini file doesn't fix the issue, so I just inserted a Return before any of the code in the ~$MButton Up:: routine on line 621

Yikes! I discovered there is also a ~$MButton:: routine at line 896. I just commented them both out to get rid of the problem.

I don't have this issue.

I have the same problem, it also double middle mouse clicks when trying to use fullscreen in PotPlayer or KMPlayer .
