Was I remembering correctly what I thought that I had read before? Ink Desktop allows writing on the desktop only and does not allow inserting the ink. What I glean from nnthemperor's post is that even it and Microsoft's Write Anywhere don't allow using the top of the pen to erase ink. In that case, perhaps there isn't currently any software that does that aside from the later versions of Tablet PC Input Panel. Earlier, I uninstalled MyScript Stylus (because its keyboard does not send keystrokes to one of my music players) and installed and uninstalled ritePen because it didn't have the option to manually insert ink. I am using Tablet PC Input Panel.
