Thanks for reporting this issue. We haven't heard of any problems with multi-touch on the Motorola Defy before, but we are working on a fix for Cogs right now that will address general issues with multi-touch. This fix may be able to resolve your issue. I don't have an ETA on it, but it'll be in the next update, and we're hoping to get that out in the near future. We'll keep an eye out for more reports.
