Mac OS X utility for resizing windows from any side?
Solution 1:
This tool allows you to do this i think and provides keyboard shortcuts.

Solution 2:
I use better touch tool for window moving and resizing. Using keyboard shortcuts in combination with mouse movements anywhere over the window is less fiddly than trying to grab the side of a window.
