Re: Bluetooth mouse lag
Not sure which Logitech nano-xmitter mouse I am using,but it uses the IR laser (no red light coming from bottom). In fact, this mouse was left in the rain for a week - I found it, let it dry in the sun, turned it on. I didn't see any light on the bottom, so thought it was broken, but plugged it into Fedora 13 instead and was pleasantly surprised to find that it works automatically - I have it plugged in constantly, so it is there on power-up - never used the BT pairing on it. I had the 'wake-up' problem, where I would have to move the mouse a bit to get it working after it sat for a while, but never had the slowness or delay. With Fedora 13 I haven't even had that problem.
I have had, on the other hand, a real delay sometimes in the latest Firefox (3.6.3) -- seems to be happening when trying to load the "junk URLs" on a site (you know the ones that do all the advertising...)
