Unfortunately I'm already doing that without success  ;-(
It's so odd.
I have one other odd thing and I'm wondering if this is normal ...

Immediately after installing VisualAge 3.0 on Win or Linux and running it
for the first time,
I get 6 errors in com.sun.java.swing.plaf.mac, which VisualAge ships with
and won't let me delete.

They are the installListeners and uninstallListeners in Mac UI classes.  The
errors say, for example,  "the method installListeners invoked for type
com.sun.java.swing.plaf.basic.BasicButtonUI with arguments
(com.sun.java.swing.JComponent) is not defined" ...

I'm downloading VisualAge directly from the IBM site so I find this most
strange.
The "about visual age" says it's version 3.0 using JDK 1.1.7 and JFC 1.0.3,
but I've seen this same problem in the Java 2 version too.
