I have an odd issue, that from my knowledge has only started recently. That is that my left mouse button lags quite a bit. This is most notable when i drag windows, as it would randomly select another window under the one i was dragging. Recently, it hasnt been clicking properly, i would have to hold the button down for a shot while (only a very shot moment, but it is very annoying and noticable) for it to click. I have an A4 Tech x7 lasermouse that has been working perfectly for years, it is only in the last few days that this problem has been occuring. I have ran virus scans and checked mouse settings in control panel without success. Any help would be greatly appreciated, thanks.
