There are 2 bugs in dolphin 7 beta 3 release. The first bug is that when you try to add a google adsense banner, it will not let you add the banner and the "url" portion should not be a mandatory field.
Bug 2 is a bigger problem. when a user creates a profile, it works great until they add a "site" to "sites". after the "site" is added, the profile just shows up as a blank page. and if you delete the "site", the profile does not come back.
so far these are 2 I found.
