I upgraded my machine and my wife's (identical hardware and version of Vista. My wife's works fine. Mine is OK on some pdf files, but blanks the Reader window below the window header with documents showing the word SECURED in the file name at the top of the window. Any further mouse activity gets a "Not Responding" message in the header. The only difference I am aware of is my security settings are tougher than my wife's. I would apprecate know which settings to tweak or where to find a copy of Reader 9. Thanks.
Try once after disabling protected mode:
1. Launch reader
2. Go to Edit -> Preferences -> General
3. Uncheck the check box provided as "Enable protected mode at start up"
4. Quit Reader and then try opening those secured files
Problem solved. Thanks very much Inayal.
Thank you very much, Inayal. That solved my headache with Reader X as well. Good stuff.
