Hi, I am making some enhancements to Insight-5.1.1. Insight uses Tcl 8.0, (which gets installed along with Insight). I want to use Tcl 8.3 instead, since I want to use some Tcl functions which are present in Tcl8.3 but not in Tcl8.0. Tcl 8.3 is installed on my machine but insight is not using it. Can someone tell me how I can make Insight use Tcl8.3. Thanks, Satya
