I am running Windows Vista Home Premium on my current HP computer, and i am using the keyboard that came with it. On it there are a series of shortcut keys that can be programmed to open s web browser, email client, search window etc. and they had been working on and off for a while when i first got it and now for about a month or even longer they have completely stopped working. I have tried to update the driver and it says that it is up to date. i have tried unplugging it and rebooting and that has not worked either. Has anyone else had this happen or have friends that have had issues? Thanks.
