Unable to save using custom form in Public folder?

Question

Hi,
Years ago I created a custom form for a Public calendar folder.  Recently I was asked to update that custom form, which I did.  Then I published it to the Public folder and changed the properties of the folder to use the new form as the default.
This all seemed to work, when we create a new record we get the custom form.  Problem is when we try to Save & Close I get the following error message:
"The item cannot be saved to this folder.  The folder was deleted or moved, or you do not have permission.  Do you want to save a copy of it in the default folder for the item."
If I hit "Yes" I think it saves in my personal calendar folder, if I hit "No" it just goes away.
I've been Googling this for a number of hours but all I find it reference to an old MS article about the mail box being full, which it isn't.
If I switch back to the original custom form I can save records all day long.  Which indicates to me that I actually do have rights and that the mail box isn't full.  I have owner rights to this Public calendar.
Any other thoughts?  I did try clearing the forms cache but that didn't seem to have any affect.
Incidentally, I was also asked to update a customized form on a different Public calendar folder and that went off without a hitch. 
Thanks in advance,
Linn

Make sure you have the right values in the Authentication Plugins in your Custom Form Authentication Scheme. You may have used different field names in your HTML form than the ones that are in your Plugins. Also, make sure the webgate.dll is protected by a Policy Domain. If all is set up right, and it still doesnt work, bounce everything including the IIS server.
I have seen situations with IIS where changes in the Access Server configuration are not picked up until you bounce the webgate / IIS server. This doesnt seem to be the case with Apache or Sun JSWS.
