I've run into some strange bug where an application randomly flash
exits once I select over 154 items in a tixScrolledListBox. The
flash exit leaves with messages concerning also
Tk_CreateErrorHandler failing and Tcl_Panic being invoked! The
application terminates with the Abort signal.

I found that the problem is remedied by configuring this widget with
the "-exportselection false" option. This makes me believe there is
something funny with the clip mechanism between tix and the X
selection. The limit of 154 is specific to this one widget and I
found a limit of 300 or so items for another widget in the
application (before weird things happen).

Is this a known problem? Has it been fixed in tix8.1?

It seems to occur less frequently with the more modern packages under
RedHat Enterprise 3.0. We need to support this application on RH 7.3
though so I'm very curious about this! Thanks for any info out there-
