I appreciate the feedback!
A friend burned CM7 on the SD for me, so I lack some details.
The mod version is 7.0.3-encore, Build # GR140. Do I need one of the more recent nightlies?
I have already tried changed the density to 160 using LCD Resolution, and clearing the cache on Market-- Also reverted to earlier version of Market-- to no avail.
[Since CM7 is on the SD, I'm using the stock system to access Google Books--& Angry Birds Rio!
