Hi,
GuiBuilder is still in alfa stage, a lot of quick&dirty work was done just
before release. A lot of work must be done before ROOT pro-release.
If possible try CVS version. .. and please describe reproducable procedure
how to crash it (on which paltform, what is an errror mesage etc.)
Thanks. Regards. Valeriy
