Re: Active Graph (Blt_ZoomStack) error

[Ken Cline]

Steve,

I can't offer you much help except to add that I've received
almost the same exact error when I accidentally killed a
probe window while running heatbugs.  The only difference
between the error messages was that mine did not contained
references to Blt_ZoomStack, but some other object instead.

I haven't had time to look into my error further but I have
2 working theories about it: either (a) I made a mistake
during my recent installation of tcl7.6/tk4.2, BLT2.1,
libtclobjc1.1b6, and swarm-1.0.2 (I would suspect
libtclobjc), or (b) this is what you get for killing a
widget during execution.  (BTW, I'm on a solaris platform)

Bottom line: You're not alone and good luck!

Sorry I can't help more.

Ken.
