Removing Somthing from taskbar

[Madhav]

Hi Guys

I was just wondering that is it possible to remove some window from the taskbar

For EG - If i open Opera, open some website and then minimize it, It just goes down to the

taskbar, Now i want the tray to hide i mean i just want its process running and dont want

it to appear on the taskbar

Hope there is a way to do that

and i hope i was clear
