I am experiencing an issue where a web based application crashes Pocket Internet Explorer.  This occurs on both Pocket PC 2003 and Windows Mobile OS.  When a user taps on a "Sign on" button after entering the user ID and password, PIE crashes and is no longer listed as a running program.  The only two ways I have been able to resolve this issue is to cold boot the terminal or go into Tools->Options and tap the "Delete Files" button.  I'd like to automate the purge of the cache some way so that it is transparent to the end user.  Is there any registry key or a command that I can issue to emulate the "Delete Files" button?  Any suggestions are welcome.  Thank you.
