"LX5 CORDLESS OPTICAL MOUSE" and "S510 KEYBOARD" are what I bought. I have a 2007 WINDOWS VISTA HOME PREMIUM with 32 bit Operating System. The computer goes bonkers crazy and can't control the side bar. When I work on Photoshop it makes my graphics go to the side all the way on their own so can't catch them to do work on them. Can't copy paste stuff b/c it won't allow me to highlight text. When writing it also goes crazy and wants to go all the way to the bottom of the page by itself. What can I do to fix it? :( Please help me.... I think it must be the driver. I used to use a driver which I downloaded online and a year ago I installed the one from the disk which came with the box when I bought the whole thing but the one from the disk (which is the original version it came with to install) seems to be worse! The whole thing is just unbearable and out of control. Please tell me what to do? Thanks in advance. Elle
