I to have tried other mice (Logitech/Cyberpower Mouse/Dell), and I believe artziz Razer Blade refers to a brand of laptop/pc not mouse. i have also stripped out as much as I can in the way of drivers for my current mouse, as i don't use it for gaming and don't need all the extra features. (Why don't i just use a non-gaming mouse? The feel and reliability.)
As far as inability to replicate... as far as my concern goes it is so random that sometimes it'll take 100's of clicks, and sometimes it take only a few... I just sat here while typing trying to get it to do it again while I was recording my screen and nothing for almost 10 mins... But as soon as i gave up and stopped recording it stuck... You can imagine my dismay..... I started the recording again and nothing.... Its a pesky little bug... Which is what makes it so annoying because its just so random, and does not follow any patterns.
I would suggest having an option to lock tab positions so they can't move period until unlocked which I think would be nice regardless of bug.
I'll also point out I usually have upwards of 15-20 different sets of grouped items going at 1 time in about 3-5 different windows... Could it be happening because of way to many groups, of an assortment of different programs/apps? (My system has enough RAM and CPU power to handle it with ease, but can Groupy without causing bugs)
I also leave these items grouped and setup for a few weeks before restarting PC, however bugs occur even after a restart.
