Anyone browsing WP with A BlackBerry PlayBook?

When I first started to use my PlayBook to browse WP it would seamlessly login to my account. More recently and perhaps consecutive with OS upgrades to version 2, I now have to manually login each time I open WP in the native browser. Other forums login automatically. Do other PlayBook users have a similar problem and if so, have you been able to create a workaround?

Thanks, Tim

have actually found my account loggin out using my Windows 7 laptop and Chrome browser.

not such a big deal for me on windows, but it has happened a couple times recently.
