Right-click shenanigans in Scarletfire build

I am trying out the Scarletfire build, 2013.7.10, on Win7 64-bit. So far, so good, except for one thing:

Right-clicking on any file or folder (like in the Transfers or Search tab) is intermittently being treated as a right click followed by left click.

For some clicks, it works OK and I get the context menu like normal. Other times, the context menu pops up, but immediately disappears, and Soulseek acts as if I left-clicked on the first item in the menu.

This is kind of a dealbreaker, as it has resulted in accidentally queuing folders or opening downloaded files.

Never had this problem in the previous builds.

I'm unable to reproduce this. Is anyone else getting this?

It seems there's actually a physical problem with my mouse. I did some more testing in the mouse control panel, and discovered that the right-click button is actually double-clicking sometimes, even though I only pressed it once.

I think maybe the new build is processing these accidental double-right-clicks differently than the old. If you double-right-click in the old build, does it open the context menu and select the first item, or does it just open the context menu?

Anyway, I followed the instructions at http://www.instructables.com/id/Repair-mouse-with-double-click-problem/?... to disassemble and increase the tension on the click mechanism. Although it may only be temporary, now a single right-click doesn't produce a double-click, so my problem is "solved".
