How can I resize a window that doesn't have the grabbing part on the bottom right?

Question

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.

Answer 1

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
• Zooom/2

I use MercuryMover for move or resize windows with keyboard.

MercuryMover is a utility designed to help you keep your hands on the keyboard. Installed as a System Preferences panel, MercuryMover makes it possible to move and resize windows using just the keyboard.
