Subject says it all.
When blank line is selected, Entry Detail window is blank, 'Add to Zone' and 'More Info' buttons are greyed out.
'About' sez I have: ZoneAlarm version:6.5.737.000 / TrueVector version:6.5.737.000 / Driver version:6.5.737.000
Anything to worry about? TIA for help/advice.

Operating System:Windows XP Home Edition
Product Name:ZoneAlarm (Free)
Software Version:6.5
