First off I love this plug-in. You guys are going a great job!
There is one issue that has been a recurring problem now for quite some time. When trying to load the stock manager, it is a very heavy burden on my host and drains all the resources. It then frequently gives me 404 or 524 errors and I have to contact my host to free up resources because my site was blocked. This issue ONLY happens when loading the stock manager. It doesn't happen all the time and seems to only happen from certain computers but its been on going for quite some time.
