The browser is failing when it encounters data that is not KpixDataRecord (as best I can tell). It will throw this error message for the first few events and then when it encounters a data record it works fine. Then it eventually fails again when it encounters another non-data record.

We are using jas 3.0.3

I'm including a few screenshots.

Also, would it be possible for the reader to have a cache of events. It would be nice to rewind if you're clicking through events and accidentally pass something interesting.
