Taskbar won't hide

[AllanP]

My task bar is set to hide, but won't. I think I've figured out what causes it, but not how to fix. It's been going on for some time and usually rebooting gave a temporary solution. I could never figure out what caused it ; it would just all of a sudden not hide. Well I just did a scan using my HP OfficeJet Pro 6810 and now the task bar is stuck open again.
I haven't tried yet, but it could also happen using the HP 6810 to print as well. So I guess HP is taking control of the task bar.

Do they show an icon in the system tray? Can the option be set to not show a tray icon? I am thinking maybe it disables AutoHide because it wants you to see the tray icon. Just guessing.

Thanks for the reply. I should have marked it solved, but I just accidentally found the problem. i was running an uninstall program (Geek) and noticed that there were two Adobe Flash installs. I uninstalled the oldest and it's been fine since. So it wasn't HP.

Cool. Glad it is working.

Back to the drawing board

Well it's back to locking the taskbar in open position. Actually it's been doing it for a while. I thought I had it licked by uninstalling one of Adobe Flash. I just can't seem to determine when it happens; there doesn't appear to be any relevance to opening anything in particular. It's locked open now and I didn't have a browser opened when it did. If I reboot it's OK for a while; could be five minutes or five hours, but always more than once a day.

Are you running Windows Sync Center by any chance?

I don't see any sign of it; plus there doesn't seem to be a way of disabling it if it is running.
