Anyone else notice that their call log is wiped periodically? For me, about once a day I will unlock my Droid and notice that I have no records in my call log. When this happens, I'll also notice that when trying to dial a contact with multiple phone numbers, the "Remember this selection" checkbox that I had previously checked on the preferred number seems to have been cleared and I must (again) select which number is the contact's default. There is no noticed rebooted and crashing before or after this happens...really no odd activity at all...I just notice it about every day during the course of normal use. Is this a known issue?
