I am using a managed code InfoPath application with a WSS form library, and
having an issue with WSS locking a form and not releasing it, at least not
when the form is closed. I have several custom buttons on a toolbar on my
form for submitting the form, and after the form is submitted I close it.
When I close the form from managed code, that's where the problem starts.
When I open the form again from the form library, I get a message saying

"This form cannot be filled out, either because you do not have
adequate
permissions, another user has the form open, or the form is open in
another
program. Do you want to open a read-only version of this form?"

Is there any way to force WSS to release the lock, or anyone have any
suggestions? I have tried several different ways of closing the form, but
same results. Very frustrating, because the previous application I wrote
used basically the same method to close the form and I've never had any
locking problems.
