[Zope] PCGI Timeout

Hi, Does anyone have any idea how to stop the pcgi wrapper timing out when zope is trundling through a long operation? I don't have access to a windows C compiler either, so I hope I'm not down on my luck here... I've been forced to use IIS on windows 2000, although this is actually working fine other than this timeout thing. If anyone else is trying to use IIS, there's a rewrite tool from qwerksoft <www.qwerksoft.com> which can be used with pcgi to do all the usual rewriting. You have to pay for it (I'm not on commission) but I've found it to be good. Thanks for any help on this timeout issue at all. Miles
