For around a year I have had an issue with my USB mouse's middle button action whilst browsing the web. Essentially if I use the middle button to open any link, about 5% of the time it will open two new tabs instead of just one. Equally, if I use the middle button to close a tab, it can sometimes mistakenly close two tabs which I then have to restore with Control + Shift + T.
What might be causing this? Here's what I've tried so far, but with the same results:
- Swapping the mouse with two other mice
- Using Internet Explorer in place of Chrome
- Running Windows in safe mode
I have now tried a spare PS/2 mouse I had, and so far I haven't been able to reproduce the behaviour after five hours (I normally see it at least once per 30 minutes). Could this really be a USB issue?
