Selected Test Results (selected in 'Test Results' table below)
DRM features for ebooks protected with "protectPDF" (YAY!!!)
Find, copy text
You must use the native msvrt.dll or reader will crash.
What does not
Some text on the tabs don't show
Preferences window shows nothing
Printing (tested to cups_pdf and HPLJ4) shows lots of postscript garbage.
What was not tested
use wincfg to override the msvrt.dll to native only.
I use reader for protected documents for school, windows was the only way until now. Hooray for Linux. I can scroll, copy and comment like I do in windows, just no printing which is fine.
