I don't know what is going on with my computer. The first thing I noticed a few weeks ago was that sometimes my sound does not work. But when that happens, when I restart it works fine. I leave my pc on almost always. I have up to the minute virus protection (Norton Online) and Zone Alarm firewall. My operating system is WinXP Pro. I noticed over the past week, when I had to reboot for something, I got an error that said, "Error loading (or starting, can't remember) OPXApp.exe. I know that can have something to do with a password manager, but I have not installed one of those. When I reboot again it usually boots ok. Only once did I get the error two times in a row. And I notice some other programs don't run correctly at times, just like the sound, until I reboot again. Do you have any idea what could be going on??? Thanks!
