No, it's not a show stopper, however it is a pain when working with raw data in the development environment. Not a great big pain, but I hadn't noticed it before SP1 and was wondering if this is a bug introduced in SP1.

actually I can repro the error, but I always switch to another record, or close the memo window, so I never noticed the error. Also since I only use browse for managing raw data, and never in applications, I don't think this is any show-stopper.
