Default unable to save new contacts

hello all. i've searched the forum for the answer to this, but i haven't been able to come up with anything.

i am running PDAVIET .15 on a Tmo Wing with touchflo. after installing the pocketCM contact manager, i noticed that i couldn't save new outlook contacts in the phone. syncing with my desktop outlook and moving contacts that way still worked, but actually trying to create a new contact didn't work.

eventually i decided to uninstall the pocketCM program and revert back to default WM6 contact manager. i still seem to have the same problem. after filling out all the requisite info for the contact, i push ok at the top right and it simply exits the contact manager and returns to the Today screen. syncing still works.

on another note, i've noticed similar symptoms in other areas of the phone. somtimes when i create a new note and click on ok to save it, it exits Notes completely...without saving.

anybody have similar problems? any ideas?
