[Zope-dev] Unexpected IOError / print in external Product class

Just recently my Zope instance started giving IOErrors when using "print" from a custom Product.. we've been using print for debugging purposes and up until now, this has worked well.. It doesn't IOError every time, though.. in fact, it appears to only IOError every second time when it hits print... so a page reload will succeed. At the moment I'm baffled, and am assuming it's a strange zope occurance which I hope someone else has encountered before, and solved. Zope version is 2.5.0. Cheers, Rob -- Your mistakes are the only thing you'll ever truly own. Everything else someone will take credit for.
