Thanks for this report. From the symptoms you describe, it sounds like you may have discovered a server-side memory retention bug. I believe you're just using the scorecarding feature, is that correct?
The application has experienced an internal inconsistency. Please contact SQLPower Support.
When you see one of these, there's a stack trace available. We'd really appreciate if you could send these to us, especially when the problem is reproducible. If you view the page source (On mac, it's Command-U on Firefox and Option-Command-U on Safari), you will see the stack trace. You might have to scroll down to see it.
