If you are addicted to dual-monitor setup then we have got a tiny little utility called ‘Monman’ which would give each monitor its own taskbar. Most of the internet geeks and developer often have dual-monitor setup and i guess this utility would be pretty helpful for them.

Monman is pretty young project and developer claims that it won’t crash on you. However as a precautionary measure don’t use it while you are working on any important document. This tiny application only appear in the taskbar for the monitor they are on. Since Dual monitors don’t have built-in function to display taskbar for you on each monitor therefore I am very much inclined towards this application.
Feature:
- Gives each monitor its own taskbar on Dual-monitor setup
- Resides in taskbar on the monitor they are on.
- Full theme support; looks just like the real taskbar
- Small, fast and lightweight. Under 125KB. No feature bloat.

Well I have tried the Multimon from Oscar but it keeps up messing with the positions of by icons. I tried MonMan it is good
I’d recommed to take a look at Actual Multiple Monitors (http://www.actualtools.com/multiplemonitors/).
Version 2.0 of this software not only adds taskbars on the seconday monitor(s), but also displays the Start button, clock and even tray icons (notification area) on these taskbars. The secondary taskbars are compatible with XP, Vista and Windows 7.
AMM is a shareware, it costs $29,95, but it has a 30-days free trial period.
