NullPointerException trying to access resource doc

Hi all,
in the Edit Resource Window I encountered an exception when:
0. edit a Resource from Resource Tree, i.e. 'RelNotes.html'
1. select any frames, i.e. 'HTTPFrame (frame-0)'
2. invoking 'Help -> Show reference documentation'

the error dialog title says "java.net.MalformedURLException"
while its message is "java.lang.NullPointerException"

The error doesn't show up when invoking the 'info' menu item
in the popup menu or when de-selecting the resource (Ctrl-Space)
and 2. above ...


Hope it helps
Bye
