I am running WP 3.4.2, WP e-Commerce 220.127.116.11, PHP 5.2.17, MySQL 5.1.50.
I try to install the upgrade for WP e-Commerce 18.104.22.168 via WP's dashboard, but it seems to hang and not do anything. I have to manually delete the .maintenance file after several minutes. It doesn't seem to have actually done anything in the meantime. Anyone else run into something similar?
