My new wireless mouse sleeps after a few minutes to save power. Waking it requires clicking a button. The problem is the mouse then sends the click to my PC. If my mouse happens to be over a button, the button gets clicked. If it's over another window, the computer switches windows.
I often can't locate the mouse cursor without moving the mouse, and the mouse doesn't move when it's sleeping, so it's difficult to avoid clicking random things. Using the right or middle mouse buttons is less problematic, but still does stuff I don't want, switching windows or entering panning mode.
I'd prefer it if a click that wakes the mouse wasn't sent on to the PC. Do any wireless mice work that way? Maybe the cheap one I got is just poorly designed.
