alright so before you guys start yelling at me i've tried to search for other solutions and so far none of them have worked.
i have a laptop with windows 8 64bit. a while ago, my old mouse went forget, and i had to get a new one - from what i can tell on the serial label, an intex sls3, no longer listed on their site.
all was fine and well but almost immediately after i started having weird mouse problems. the most proeminent is this one: i often lock focus to the current window - not being able to click the taskbar, or any other window - and if i alt-tab to another window, clicking on that just changes focus back to the starting window, no matter where that is. it happens most often on firefox, and a lot of the time it happens when i middle click something.
i also have other issues involving the mouse, including google chrome going completely forget, opening new tabs when i click on links, and closing those tabs when i try to switch to them.
the only way i can see to fix these problems is to press ctrl-esc once, bringing up the metro menu, then pressing it again to go back to the desktop.
the problem also happens regardless of whether my mouse is plugged in or not, and also happens in safe mode.
