SMS Sent Messages Only Showing

Only my side of the conversation is being shown under messages...

Motorola Milestone X
Droid: 2.3.5

PC:
Win 7 x64
IE 9, Ffox 8.0.1

My problem is similar, but not consistently so. The sender's messages appear in the message list as long as I open the thread after the conversation has already started outside AirDroid. From that point on, only my sent messages appear while the sender's messages never appear (except on my phone).
Moto Droid Razr (2.3.6) on Verizon
MacBook Pro 10.7.3 Google Chrome

Even the upper-right "Refresh" button doesn't help?
