CTRL-SHIFT-DELETE key combo will bring up the screen for clearing cache in any browser.
Spedforms recommends using the Chrome browser for best performance.
Close and re-open the browser after you do this.
Clearing browser cache helps to clean everything up and will resolve many odd issues. Do this if your Spedforms is behaving badly - for example screens closing unexpectedly, passwords locked out and you are sure you are using the correct one, text formatted with garbled characters. It also will fix issues of data disappearing when you enter it in Student Setup.
