I bought a new Logitech keyboard and Optical Mouse. The keyboard installed OK, but I cannot install the mouse and had to go back to using the old one. I've run the software several times and it appears to be installed, but when the computer re-starts, the window comes up saying it cannot detect a mouse. I did have to buy an adapter to use the new mouse on my computer. Would that have anything to do with not being able to install? I've checked several times, and the adapter is tight, etc. If anyone has any suggestions, I would certainly appreciate any help. Thanks
