Hi. I am in a TCL app and I'd like a second copy of the program to open and to run in a window. Is this possible, is this advisable? If so, how can this be done? The app is Notebook written by Bill Duquette. Thanks for the info.

[AMG]: One method: use [exec].  To run the second program in the background (i.e. not have the first wait for the second to terminate), give & as the last argument to exec.

Another method: check if the program supports multiple "logical instances" within a single process.  If it keeps its state in global variables, it probably does not.  But if it was designed to be used as a [megawidget], it probably does.  If multiple instances are possible, create a new [toplevel] and put it in there.  Thanks to his [Snit] experience, [WHD] is more likely than most to design his programs as megawidgets. :^)
