Hi... At least since the insight intree supplied tk 8.4 version there is bgerror handling script coming with tk. libgui has its own version, which is also not so nice than the tk version. The attached patch removes it in favor ot the tk version. As tk 8.4 is anyway (still) the prerequisite for insight this change does not harm. 2012-03-22 Roland Schwingel * library/Makefile.in: Remove reference to bgerror.tcl. * library/tclIndex: Ditto. * library/bgerror.tcl: Removed file. Any comments? Is this ok? Roland
