[Zope] tpc_begin

Hi there, Firstly, I'm not a member of this mailing list, although I have an archive of over 2000 messages from it. Could anyone replying to my message please reply to tim_haines@hotmail.com as well as the list? Thanks. I've been developing a site using nt4, Access, and the odbc plugin. Things work great - most of the time. I've noticed that occaisionally I get any error message that mentions tpc_begin. When I do a refresh, the problem is gone, and the site works fine again. I've also noticed that this normally occurs the first time a database query is executed after a reboot. Does anyone know why this would happen, or have any insights at all? I look forward to hearing from you. Tim.
