Bernhard, I am unsure of usage, but made TableMorph a PluggableScrollPane to simplify a bit. Examples looked OK. Check #initialize, #adjustExtent (FYI: I don't understand intent here), and #layoutMorph. I am not a big user of PluggableScrollPane, so I probably screwed something up, so please let me know. Try resize halo handle. Thanks, -KenD
