Vista Calculator is a lightweight widget that displays a small calculator application on your desktop. It can be easily installed and configured, even by users with no experience in widgets.
The interface of the tool is based on a small frame that you can move to any position on the screen with the help of the mouse cursor.
The calculator integrates only the standard functions, so there is no advanced area available. Unfortunately, you cannot use the standard keyboard or numeric pad to make calculations.
Vista Calculator does not come with any configurable settings of its own. But, thanks to some options provided by the operating system, you can open the right-click menu to make some modifications. For example, you can make Vista Calculator's frame stay on top of all the other windows, as well as adjust it opacity level between 20% and 100%.
The small widget is not a concern for the computer's resources, as it requires a low amount of CPU and system memory. It is very responsive to commands and worked fine during our tests; we have not come across any errors and Vista Calculator did not freeze or crash. All in all, Vista Calculator is a useful tool for making quick mathematical calculations directly from your desktop. No recent updates have been made.
