It is not supposed to be unsafe at tcl level, as it supports several interpreters side by side in the same application. It is unsafe at user level, precisely because creating a StringVar might put it in the interpreter you don't want, leading to weird errors and unexpected results. So you *can* use several Tk instances in the same application, but then you really should specify a master for absolutely everything, or you'll get bitten at some point. > Thanks! > Alan Isaac YW.
