Drag and Drop to another program

[Mark Strickland]

I have a program (no source) that lets me drag an item from a ListBox and drop it on a TextBox in another program to fill it in.  When the Drop is done it pops up a context menu and you can pick one of several options of what to drop.  (It is actually a password keeper program once published by PCmag).

Have any ideas how this might be done in FF?

Any help with Drag and Drop in general would be appreciated.

Thanks.
