Solve the Blank Form Mystery
When was the last time you filled out a form on a web page and clicked Submit,
only to be told there??™s something wrong with what you??™ve entered? You
do as you??™re told and click the Back button to return to the previous page,
but now the form is completely empty.
This is caused by a bug in your web browser, not the web site. All versions
of Internet Explorer, and older releases of Netscape (versions 4.x and earlier)
exhibit this bug. Browsers based on the Mozilla engine, such as Firefox
and SeaMonkey, are better at saving form information, except under certain
circumstances. For instance, if a form is generated on the fly, Mozilla browsers
usually can??™t save the text you??™ve typed into it.
To date, no browser handles form data in previously visited pages perfectly,
but there are a few workarounds.

For one, most web site designers are aware of the bug, and have built their
web sites accordingly. So, if you submit a form, and need to go back and
change what you??™ve typed, don??™t press your browser??™s Back button. Rather,
look for a Back button or Edit button right on the page, and click it to safely
modify your text.
Next, make a habit of performing an impromptu backup before you submit
any form. For instance, if you??™ve written a long message, click in the text
box, press Ctrl-A to highlight all the text, press Ctrl-C to copy it, open
Notepad, and press Ctrl-V to paste.
