Thanks a lot for your feedback
Let me address your issues:
To 1: Good point the Session time field needs to be grayed out if encryption is disabled. It is ignored if encryption is disabled because the login and logout is disabled as well in this case
To 2: Thanks I will do some more testing here. But for your info, the original PocketPassword exe file is overwritten. It detects old installations if A) the file SecurePwdData.txt exists in the folder AND PocketPasswords 1.0 settings exist.
To 3: That's very strange, I tried that and on my PPC it has overwritten the 1.0 icon with the new one. Which PocketPC WIindows Version do you have?
