Seems to be experiencing a weird problem where my mobile app doesn't seem to want to sign out the session. I've tried both FormsAuthentication.SignOut() and MobileFormsAuthentication.SignOut() and neither seem to work, although I did try with IE (desktop) and both worked fine, so the issue is isolated to my mobile device (Blackberry 6750) If I close the browser and re-open the web site I'm logged in again, the only way it seems to get logged out is if I let the session timeout. Anyone else experience this? Or have some ideas? Cheers! - Sean
