We upgraded this weekend to Service Pack 3 and also installed the patch 70517 and we are having problems with a upload and update process we have written.  The process basically copies a file to a directory (diff per user) and then uploades the file to Teamsite and calls a workflow process.
After the upgrade of the SP and patch the link that calls the upload/workflow process is failing and we get reidrected to the main page.  We believe the proble is with (iw.base.show_done_page?) as we call the following 
/iw-cc/command/iw.base.show_done_page?full_redirect=true&done_page=\stat\tsWASLogin.pl%3Ffile%3Dwas01b%5Cwdiaaear.ear.  This then redirects us to 
/iw-cc/command/iw.ui instead of kicking off the workflow. 
Has anything changed with this (iw.base.show_done_page?) with SP3 or the patch that would cause this problem?  Anyone else seen similar issues?
