I have a Logitech G5 (Wired/Laser) mouse and I'm using an up-to-date install of Fedora 8 - in fact I've reinstalled Fedora once already, hoping this problem would somehow go away. I've also tried searching Google obsessively for a solution, and the closest I can find is some possibly unrelated, unresolved ubuntu issues from a few years back.
A few days after installing Fedora, the left mouse button suddenly starts behaving completely irratically. It only occurs when you're holding the left mouse button down - it's as if the mouse driver ceases to detect the click and then redetects it completely randomly.
The easiest way to demonstrate it is to simply attempt to click and drag across the desktop. It will begin drawing the box around the area you're selecting, but within a second or two it'll act like you instantly let go of the mouse button, and then began holding it down again, effectively drawing a whole new box from scratch as you drag the mouse across the screen. This behavior will occur repeatedly in one click-and-drag pass across the desktop.
If you attempt to drag a Sticky Note across the screen, you notice that the intermittent detect-and-lose-the-left-click happens so fast and so often that it quickly detects a double click instead of the intended dragging motion.
Again, there aren't any problems immediately after I install Fedora (it even works fine after all updates are installed). A few days later, the problems start. I assume it *could* an update causing it, but I don't really see how because I assume that it should have began again immediately after I patched up my most recent Fedora installation - and it didn't (unless, it started after reboot, etc, but I didn't notice that to be the case).
I'm hoping its a simple fix, so thanks for the help!
Another day or two of this and I'm going to go insane and head back to XP (Fedora is the only distro that comes close to being stable / usable on my machine.. until this problem sets in).
