Missing cw3215mt.dll (or missing cw3215.dll)
Sometimes, when using Tkinter on Windows, you get an error that cw3215mt.dll or cw3215.dll is missing.
Cause: you have an old Tcl/Tk DLL built with cygwin in your path (probably C:\Windows). You must use the Tcl/Tk DLLs from the standard Tcl/Tk installation (Python 1.5.2 comes with one).
