Hmm, now I'm confused again.
When I make changes to a form in an add-in and save changes, the change is not showing up when I reinstall the addin. How do you ensure the .ppa file has the most recent changes if you're editing the .ppa file directly?
[EDIT] -- it's not just form edits.. it's code too. So it must be opening an old version of the file somehow when I reinstall? Man this is confusing.
