How can I resize a window that doesn't have the grabbing part on the bottom right? I have Hulu desktop running and I want to make the window smaller, there are no lines which are usually present on windows for resizing on the bottom right corner, though. On windows I could right-click the title bar and choose size for these kind of windows, is there any way to do something similar on a Mac?

I tried pressing the green button on the top left, but that doesn't do anything.
Hard to find free softwares for this, I only found a donationware :


Window Wrangler


Otherwise, you can have paid solutions :


Cinch, which a nice and useful windows manager.
MondoMouse
