Mouse Up lost after Right Mouse Button + ScrollWheel trigger, leaving RMB held

I have a normal mouse trigger set to RMB + ScrollDown. I use this with the keyboard action Command+DownArrow to scroll to the bottom of a page. I use this in browsers.

The problem is the RMB remains held down after this action executes. I have another mouse chord trigger for Hold RMB + press LMB to send Command+W to close my current tab, and this consistently triggers the next time I press the LMB on its own.

I tried various ways to fix this, including custom actions to send RMB up only, which does cause it to release, but this triggers the RMB menu in my browser. I can then fix that by adding a 0.2s delay then a keyboard trigger for Escape to close the menu, but this is obviously a very poor solution.

This feels like a bug. Is it possible to fix?

can you check whether 6.326 (uploading now) fixes this issue for you?

@Andreas_Hegenberg related to this, I use mouse chords:

Hold right click then left click, then release rightclick: Command-W (close tab)

Hold left click then right click: Command-T (new tab)

When I do the first one (starting with RMB) in BTT, it pops up the right-click menu in the same way.

I previously used a Firefox addon Gesturefy to do this, and the latest fix to make rightclick+scroll work in BTT broke that addon entirely. I also used it for RMB+strokeleft to move to the left tab and the reverse to switch to the right tab. I’m happy to use BTT for all the above if the menu popping up could be fixed.

Is this one possible to fix also, or alternatively to not grab the RMB for all gestures so I can use Gesturefy? If not I guess I could go back to stroke right+Up in gesturefy to a open new tab and so on.

Let me know if you’d prefer a separate thread to cover it as this one is marked solved, happy to open a new one.
