I have the following problem with Word on my tablet PC: When I open
some .docx
files (usually ones I get from students, though this happened with
some of mine, though I cannot reproduce the effect), and try to "Start
Inking", the button appears to be pushed, but the Pens ribbon does not
come up, and the cursor does not change into an ink cursor, but stays
as an I-bar. No matter what I do I cannot get the darn think to let me
ink.

I have found that if I save as a Word 2003 .doc I can ink in that, or
if I save as a 2003 .doc and then immediately resave as a 2007 .docx I
can ink in that.

Interestingly, if I select all, copy, and paste into a new docx, I
cannot ink. But, if I ink in a new docx, then paste, I can ink.

I would really love some explanation, and a workaround/fix easier than
having to resave (twice) or copy-ink-paste...

Any help appreciated!
