I work with Greg, and we have "semi-solved" this problem. We called the data object's
execute from a new thread.
This has freed the swing event dispatching thread from being consumed with the data
object. So we are now able
simultaneously update swing widgets. However, we now experience a new exception that
appears to be connected
to CSpLog. The following stack trace is displayed in the Java console:
ERROR: NO LOG CONTEXT
java.lang.Exception: Stack trace

Thanks in advance for any help you can provide.
