This is the first time I heard about this problem. Have you tried to disable all other plugins for a second, and then tried to dismiss it? It sounds like there could be a JS error somewhere, which will prevent the dismiss from being saved.

Can you check for JS errors in your browser when you try to dismiss it?

Thanks for the quick response, that worked ??

Why not first open a support thread, and give me a chance to look into the issue before giving a 3 star rating? If it worked after disabling all other plugins, then it likely had nothing to do with my plugin in the first place, but with a JS error created somewhere else.
