You get a big thumbs down for making it impossible to report a bug on google spreadsheets. No, I don't want to post to a forum. Set up Bugzilla, and stop wasting 15 minutes of my (and presumably others) time bouncing all over your site looking for a way to submit a bug report.
P.S. Your array evaluation mode is busted. If it's not powerful enough to do something, failing is better than doing something arbitrary. I admittedly am not a spreadsheet guru (although I have reluctantly learned a few tricks from some).
