WF Builder dumps with latest SapGUI patch?

[Mike Pokraka]

G'Day,
Has anyone else experienced problems with the workflow builder and the
latest Gui patch?
We've just been patched up to the latest SAPGUI 6.40 patch 23. Since then
Since the patch the WF builder keeps short dumping randomly with
MESSAGE_TYPE_X. It's too random & intermittent to do a quick test on
another machine - happened 5 times today.
Oh, and running Windoze XP.

Cheers,
Mike
