Hi, At start up when restoring previously saved workspace that contains an exprSet object, the system tries to automatically load the Biobase library and comes up with the following errors about loading the Biobase menus. When I reload Biobase, everything works fine. Is this a bug? Thank you. -Christos ---------------------------------------------------------------------- ------ --------------- ...
