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?
Answer by Ingo Mierswa:
I tried both operators here on my Linux system (Kubuntu) and other systems (SuSE) and did not notice any problems with these operators here. Are you sure you use a JRE 5 from SUN? Often on Linux some free variant like gcj is used which often does not work correctly with the graphical user interface.

I just switched from Fedora to Ubuntu last week. As all the other Java applications worked fine from within the standard installation (openjdk), I didn't take this into account. After switching to Sun Java everything works fine.
