Calculations page cannot be exited without exiting the browser. Clicking on the close button on the calculations page header doesn't close the window. If multiple copies of the subnet calculator page are accessed, then multiple copies of the calculations pages will appear.
Minor. Can consume computer resources if entered multiple times. A workaround exists.
Exiting from the browser will cause all the calculations pages to also exit. Instead of starting a new copy of the Subnet Calculator each time, simply use the navigation buttons and history list within the browser to return to the previously loaded instance of the Subnet Calculator.
Changing the IP address class or the Subnet Zero option causes the menu items on the data input window to flicker.
Cosmetic. This is a cosmetic bug and does not affect the operation of the Subnet Calculator. When the menu items are updated to reflect the different number of possible subnet bits, subnets, or hosts, Java redraws the screen after each addition, causing the menu items to flicker.
No workaround is needed.
