I installed your plugin on a blog of my own and ran it, and had no problems. However, now I'm running it on a different blog for a client and for some reason, whenever I click into any of the Simple eCommerce control panel pages in the Dashboard, I can't expand any of the dropdown areas in order to do things like enter Paypal settings, add information about products, etc. In fact, the native WP dropdown menus stop working when I'm on those pages too! As soon as I go to another section of the Dashboard, they all work fine. So we'd love to use your plugin but we're dead in the water until we can configure it!
