AutoSizer - Version 1.4 AutoSizer automatically resizes any window you specify. For instance, some web browsers open up in a non-maximized window. Using AutoSizer, you can set those windows to automatically maximize every time they’re opened. It works with almost any program, including web browsers, Notepad, etc. AutoSizer stays running in the system tray (next to the time), so it stays out of your way while it works.
