Remember that BC Calc uses the browsers cache as it stores it’s ‘session data’. A web browser only has one cache; Users that need to be able to run multiple sessions at once may open a different browser (Chrome, Firefox and/or Edge) and work independently of another browser’s active session.
Another option is to use a ‘private’ browsing window. Private browsing, privacy mode or incognito mode is a privacy feature in some web browsers to disable browsing history and the web cache. Being that the private browsing window is not using cache, it will not interfere with the active session. To start a private window, navigate to the browser menu or use key commands.
Chrome: Ctrl + Shift + N
Firefox: Ctrl + Shift + P
Edge: Ctrl + Shift + P
*This might be useful if the phone rings and the caller needs help with a quick calc. The user doesn’t have to take the time to (but should) save, start a new analysis and come back to what they were doing before the call if they use a different browser or private window.
*If working in BC Calc Offline, it may be that the user is accessing the application from a desktop shortcut, which will always open in the Windows default browser; simply copy the URL from one browser window to the other, then bookmark it, so it's there next time. (=
