I have a Logitech optical USB wheel mouse I've used for years on my PC (Windows 95, 98, XP, Vista, 7): http://www.clubic.com/shopping-1360-3-logitech-wheel-mouse-optical.html I'm now using it on a Mac mini with Mac OS X Snow Leopard (fully updated), but I have a problem with it.
On my PC, when I move the mouse, the movement is smooth, and follow my hand moves. No matter if the move is large or small, the cursor goes exactly where I send it.
On my Mac, when I move the mouse, it seems to do what I want on large moves, but on little moves the cursor does not respond as well as on the PC. It seems to slow down, as if it had missed some move instructions, as if it was responding only one on two impulsions.
For example, when I try to catch the cross to close a window, I have no difficulties to reach the cross area, but to put the mouse exactly on it to close the window, it's as if I were moving the mouse on a badly responding surface. It's hard to reach the cross, like if the mouse was suddenly 2 times slower. Same problem to put the cursor beetween 2 letters on a text to make a precise selection, and other similar things. It's a nightmare!
I had tried many settings into the mouse control panel but it does not change anything on this problem.
I have also tried 3 other mouses, one wireless Logitech Mac OS compatible, one wired Microsoft and one wired Trust: all have the same problem.
What is happening? Do you know how may I solve this issue?
