Today is Technology Tuesday.
The FREE software for today is Sizer from Programs by Brian Apps.
Sizer allows you to size any window to a predefined size. If you work with multiple size screens you can change the window size of a web browser or a resizable program instantly to see what it would look like.
This is very handy for web designers as they can switch between window sizes to see what their web pages will look like in different size browsers.
Computer support folks can provide better help by resizing a program on their PC as they help remote users over the phone. Let’s say a remote user is working in Microsoft Word and their window size is 800×600 and the support person is running Microsoft Word in 1280×1024, the support person can resize their own Microsoft Word to 800×600 to “see” what the remote user sees.
Sizer parks itself in the system tray 
as two-crossed double-sided arrows icon. By right-clicking on the crossed arrows you get the configuration options for Sizer as well as some standard defined window sizes.
You can also right-click on the resize corner of a window to resize the window as show below.
And yet another quick way to resize a window is by right-clicking on the maximize button of a window as show below.
The configuration screen (show below) allows you to add and order sizes as they would appear when they pop-up during use.
The “Move to” functionality allows you to position a window when you resize it.
The program ran fine on Windows Vista even though the author says that Sizer is not supported on Vista.
