To expand on the situation a bit: I'm doing a couple of adjustments on a skin for a client. When uploading my adjusted version of the containers file, I used the Admin Extensions uploader rather than the Host Extensions uploader, not realizing that the previous version was installed through Hosts. As a result, in Extensions it shows the updated skin (v. 1.0.1), but it appears to have retained the old version as well somehow. As it stands, if you select the container with the "Site" radio button selected, you get the correct container, but if you select it with the "Host" button selected, you still get the old version. When I try to install the updated version over the old version in Host Extensions, all I get is a note that it's already installed (no option to repair). This is going to be confusing for people using the site.

My initial thought was to simply delete the container pack and reinstall it correctly, but I've run into another strange hiccup: Despite the fact that I've gone over the site with a fine toothed comb and changed every place I could find where the container was being used, Skins still claims it's in use and Extensions won't allow me to delete it. I'm trying to figure out how to proceed from here.

Thanks for the advice. I'll give that a shot.
