Re: [ANN]: TkDND 2.0 alpha...

Is dragging an e-mail from outlook the same as dragging one from
outlook express? If you install the latest TkDND 2.0 alpha 2, and
you run the dndSpy.tcl (from the TkDND 1.x demos directory),
then you can drop an e-mail from outlook express to Tk.
I tried it and it worked for me. Outlook express seems to be
using the regular types CF_UNICODETEXT & CF_TEXT (among
others), which are supported by TkDND 2.x.
