When multiple instances of a program are running (but windows are closed) in Windows 7, is there a way to have the program open by clicking the taskbar button (without having to take the extra step of clicking a thumbnail)?

I’m frustrated that Windows 7 makes me click the taskbar button and then click a thumbnail in order for the program to open. I’m wondering if there’s a way to set it up so I don’t need to do this extra click.

For example, if I have 5 instances of Internet Explorer open in Windows 7, I need to click the Internet Explorer taskbar button and then click the thumbnail of one of the windows. What I want to be able to do is click the taskbar button and automatically have the last window I was viewing open immediately. This is the way it works in XP and Vista.

I hate the need for this extra click!

Does anybody know if there’s a way to fix this?
