pgAdmin III Version: 1.18.0 (NOT a development snapshot version) Detail: when F1 key is pressed, or the menu item "Help -> Postgresql Help" is selected, or the toolbar icon "Display help on the sql commands" is clicked, the running pgAdmin will emit an error then quit.
I checked the other items in the help menu, such as "EnterpriseDB Help", "Slony Help", etc. They all seem fine. Only "Postgresql Help" will cause problem. I searched the archive, and found the same error some 5 years back and was fixed by then. It might be a regression. Thanks! -- Gang Liang Life is beautiful!
