I am still using 2007 (I have bought 2008 but not installed yet)
In Windows Add Remove Paint.net V3.22 is still showing although I have uninstalled it.
The software manager in 2007 does not list it and I have not added it to any ignore list.
Am I missing something or is it time to install 2008?
edit
never mind< I used the MSI clean-up utility
