In order to free up memory on a 9210i, I unloaded AppMan, using the AppMan menu option under "tools". When I used the icon under "extras" to start AppMan again, a blank screen came up with the Appman logo in the top left corner. Then the "Extras" screen came up with the applications icons on it ghosted with a small message saying "Note not found". I re-installed AppMan and it worked perfectly until I repeated the unloading exercise when I got the same result when attemptin to reload.
After consulation with SmartAppz - Symbianware!, I learned that this is a bug in the software that they hope to fix in the future. The interim solution is to restart the application using "system\programs\appman.exe". I have simply created a link to this file in Desk.
Despite this minor bug, I still think AppMan is a great tool and I use it all the time.
