Consulting Hours on Facebook Connect for an ASP.NET WebSite.

I am currently developing a Website targeting all kind of mobile devices and it requires FB-Connectivity , mainly to authenticate users. The login funcionality works but has some flaws I haven't been able to fix: 1.) The login pop-up screen never closes after the user has succesfully logged-in. 2.) The user has to click the log-out button more than once In order to succesfully log-out of the app. 3.) When accessing from a Blackberry device the pop-up screen never shows up. I am looking then for an alternate method to authenticate users if it is deem as necessary. I am willing to pay for a couple of hours for someone to give me a hand at this. Regards Wilfred Maynham
