Sheesh, computers are just about the worst time-sink there is. I had a keyboard (wireless) that I loved. Unfortunately the mouse died. It was wireless but was mechanical, not optical. In an attempt one morning to clean it, the insides popped out and couldn't be put back together again. Sigh. I must admit that this was already my 2d identical keyboard/mouse combo as the keyboard died on the first one and Geikie had taken a chunk out of the mouse wheel as well.
Okay, so Terry went to the store and came back with a Microsoft wireless keyboard / optical mouse combo. This was what I had requested, so I eagerly plugged it all in and away I went. Weeeelllll, no matter where I put the RF communicator, I kept getting irritating messages that either the mouse signal quality or the keyboard signal quality was too low. GRRRRRR. My recourse was to turn the damn notification off. But then the mouse just didn't work well some of the time. So what was a poor user to do? Get another mouse/keyboard of course.
First brand -- AOpen; second brand -- Microsoft; third brand -- Logitech. Cool. Except that now my mouse scrolling wouldn't work because I have my computers linked through a KVM switch (keyboard, video, mouse switch device for you non-geek readers). Of course I found out that emulating the mouse functions is not very good through KVM switches and many others had similar frustrating experiences. It's entirely brand dependent --- both on the KVM switch and the mouse brands. And on top of that, the keyboard buttons for all the extra special functions (which I don't use much) are totally mis-mapped. Press the "email" button and the "favorites" list pops up. AARRRGGGHHHH.
Some users and the help at both Logitech and Microsoft suggested unloading the specialty device drivers and using the old tried and true PS/2 compatible mouse drivers. Smile. OK. Load up the generic drivers and now a program I use a lot won't work properly. Now I'm tearing my hair out, screeching the primal scream.
So what am I doing today? Re-installing the Microsoft keyboard and mouse. I surrender. UNCLE !!!!!!
