Merlin-beta-F Swing JTextPaneTest in SwingBasher just stops typing characters part way through its paragraph on Windows 2000.

You can get SwingBasher here:
/net/sqesvr/export/disk3/Kestrel_ws/Functional/SwingBasher

To run it set JAVA_HOME and type "nmake auto" which will automatically compile it and run it in loop mode.

It won't even compile on win95/98 so I can't compare the results.

It normally runs fine with Kestrel.

Here's a trace from Windowss 2000 with Merlin b18:
