On Windows, no matter what browser you are using, hold down: Ctrl+Shift+Delete.
This will pop up a window asking what you want to delete, and what time frame if you are using Firefox or Chrome.
If you are using Chrome, select “since the beginning of time” from the drop down, and then ensure Cached Images and Files are checked and clear the cache. After the cache is cleared you can go back to the tab with the application and press Ctrl+F5 to do a hard refresh.
If you are using Firefox, select “Everything” from the drop down, and then ensure Cookies, Cache, and Offline Website Data is checked and clear the cache. After the cache is cleared you can go back to the tab with the application and press Ctrl+F5 to do a hard refresh.
If you are using Internet Explorer (Not recommended), simply ensure Temporary Internet files and website files is checked AND Cookies and website data is checked, and then click Delete.

Cache, and Offline Website Data is checked and clear the cache.After the cache is cleared you can go back to the tab with the application and press Apple+R or Command+R to do a hard refresh.
