I believe this is a very very small bug but it is a little annoying sometimes.
on the Phone Tab, I have the Dialer Pad (number pad) to auto show - so, "Start dialer without dialer pad" = unchecked.
When I slide the dialer pad down to hide it, then i go to another tab, e.g to view contacts list, and then back to the Phone Tab, the dialer pad is correctly hidden, but if i slide it up again, it will go back down automatically / instantly drop down. I then have to slide it up again, thinking I did not slide up enough, and so the 2nd time it stays up.
That is all really, its not a big issue, just annoying 1% of the time

To reproduce:
1) start with Phone Tab, and with dialer pad up and not hidden.
2) slide dialer pad down to hide the pad.
3) now click on the contacts tab or use gesture and swipe left to go to another tab.
4) now go back to the Phone Tab, and try to slide up the dialer pad. It will not stay up.
5) try to slide up the dialer pad again, and this time it will stay up.
Tested on Moto Defy, Android 2.2.2 custom rom, using DWC free v2.0.4
Can anyone reproduce this?
