I am glad you were able to confirm what is very likely a memory management problem. You probably escaped the segfault for tkdemos.tcl by chance. > > By the way tk01, tk02 and tk03 do not work correctly for me. Is this an > itcl issue? If so we should disable these for the case without itcl. I noticed your later e-mail confirming they now work okay except for a segfault at the end. tk0[124] work fine for me without that segfault on exit, but I do get that segfault for tk03. I am sure this difference between us is just random chance when there are underlying memory management issues. > > As an aside, why do we have copies of all the x??.tcl examples in the tk > examples directory?

The motivation for all x??.tcl examples in the tk examples directory is so that tkdemos.tcl will work. The examples look much better under tk/tkdemos.tcl then under tcl/tcldemos.tcl, but we want to test both. However, tk/x??.tcl should be identical copies to tcl/x??.tcl so it sounds like a build system screwup to me. I will look into that. Alan __________________________ Alan W.
