From: JimH on
I recently upgraded from Office 2003 to Office 2007 on my Gateway (sigh)
tablet PC running Windows XP Tablet. When I try to write with the stylus on
the Power Point slides (full screen mode), quite often there are stray
horizontal ink lines. The stray markings render the writing almost illegible.

I never had ink problems with PowerPoint 2003 and there are no problems when
I use Windows Journal. It only happens with PowerPoint 2007.
