Looking for a registry fix to unlock the Display PDF in Browser option. Not sure how it is greyed out to begin with. My MST file was not set to Lock anything. Please help. I cannot find anything anywhere of use to "ungrey" this option.
It seems to happen when Acrobat is installed.
How can I fix and how can I prevent in future releases??
I don't know why this is happening. Try if it still happens with the latest Reader XI.
