Windows 7 laptop, docked with a second monitor. This problem started happening when I started using the second monitor. The taskbar will often stop displaying. The Windows logo remains, but the bar, system tray, clock, and any icons for minimized programs disappear. I can see part of my desktop wallpaper where the taskbar should be. The taskbar is not set to auto-hide. Killing the explorer.exe process and starting it again temporarily fixes this. Is there a permanent solution? Thanks!
