[Zope] External Editor problem

I've been using version 0.6 and will upgrade to 0.7.2 shortly. Let me know if you've already encountered this and fixed it. Some of my users insist on using WindowsXP Home and IE. The external editor fails. Running the helper application standalone works fine. Runing Firefox as the browser works fine after a bit of fancy twostepping to get it configured. The diagnostic from IE is FATAL ERROR: [Errorno 2] No such file or directory: 'C:\\Documents and Settings\\joe\\Local Settings\\Temporary Internet Files\\Content.IE5\\11Q3QMRM\MyTest[1].zope' which appears to be a bad path in the helper application. I believe that the correct path is ...\\Local Settings\\Temp\\Temporary Internet Files\\..
