Cannot scribble (sketch) on text
I have a boox M90 with the latest firmware 1.5.1 (06/30/2011). On 99% of my PDF and EPUB I cannot scribble (sketch) on the text. On most of my books, when I select the "Annotation" the sketch option is not there..I only get: Add Annotate, Erase Annotate and All Annotations.
Any help would be greatly appreciated
