My logitech wireless keyboard has been behaving erratically for the last year or so. It is not about the connection, but key behavior (z suddenly becoming J, " becoming backspace, or --the latest-- typing correctly but from right to left). I have contacted logitech and followed every possible troubleshooting tip as far as software is concerned (I know it is not a hardware issue because wear and tear is not something that goes away and comes back multiple times). By erratic I mean that software suggestions such as reinstalling have proved effective for days, weeks and even months. Unfortunately, the last time I thought the problem was fixed it came back within minutes. Logitech has specifically suggested I contact Windows: "we already provided all the applicable troubleshooting steps for the device and still will not work, there is a probability that this can be a device driver issue since it works fine for a moment. At this point we suggest that you contact Windows technical support so that they can give you a compatible driver for the keyboard" Please advise! Thanks in advance,
