Norton Security 22.6.0.142 tray icon unresponsive

Hi, all:

Having an issue on my wife's XP Home SP3 x86 laptop where the NS tray icon doesn't respond when right-clicking to access the submenu. NS works fine when accessed via the start menu & desktop shortcut. Ran NRnR twice in the last 2 days with no result. I figure I'll need to do a nuke & reinstall, but I'd rather not have to re-do all the custom firewall rules, if possible. Thought I'd check with Forum members to see if anyone else has seen this issue. Thanks in advance for any suggestions - Brian
