Just wondering if anyone has come across this situation.

I'm using IE 6.2SP3 on Windows XPSP3 with RAP 1.3.1 running standalone with Jetty.

Occasionally we see the following exception occur:
java.lang.IllegalArgumentException: Argument cannot be null
at org.eclipse.swt.SWT.error(SWT.java:3185)
at org.eclipse.swt.SWT.error(SWT.java:3119)

It seems to happen if a user is clicking tab items faster than they can be rendered.

Any ideas?

Hi Graham,
could you test your application with 1.4 release? If the bug still
persist, please file a bugzilla with a snippet to reproduce it.
Thanks,
Ivan
