R^7Z mentioned this and you probably understand, but I thought I would clarify one point just in case. Your first screenshot is not a porting problem. You just need to scroll down to see more. Try flicking the screen up with your finger. Also, on the second screenshot, you can still type in the password even though you can't see the password field.
On the third screenshot, I'm not sure, but this file may fix that problem:
Digital Outcast's snooze options
It's mentioned in post #6 of this thread, and it basically reverts the pop up notifications to the older Windows Mobile 6.1 appearance. It's mainly to regain the multiple snooze options, but I believe it has a global effect on all those pop ups. You just have to give up the newer pretty pop ups for the more functional older ones.
