after loading "ExcelExampleSource.xml" or "CSVExampleSource.xml" and reading some EXCEL or CSV data without an error RapidMiner doesn't respond anymore and can only be closed by the kill command (Ubuntu 8.04). Can this be avoided?

Often on Linux some free variant like gcj is used which often does not work correctly with the graphical user interface.
