Maximize windows on your Mac like in Windows

For all of you, who also shifted from Windows to Mac, you might have run into the same problem:
The behaviour of the green window button seems to be like a lottery. Sometimes, the windows are maximized and sometimes they end up in a different size.

I found a freeware tool on:

to resolve this issue:

  Right Zoom for Mac 1.63 - freeware (language: English)

Independent reviews from SwitchingToMac.com and BrightHub.com

This free tool fixes an inconvenient behavior of green Zoom button in Mac OS X. It will always expand windows on a full screen instead of strange resizing.
