Thanks Kevin,
I've duplicated the issue on three boards; DX58SO2, DX79SR, and a DX58SO. Although the DX58SO is not listed as valid for the module, it works as well as the other two boards I tested.
Besides the "Send to Bluetooth" COM Add-in error box pop-up, the Bluetooth driver causes the MS Office copy text and paste a large black dot/blob/spot issue.
I read about the same Bluetooth error on another Intel board with a different Bluetooth module when I was searching for information. The other board had a Motorola driver as well.
I've seen/read enough to get the impression that Motorola needs to test their Bluetooth drivers more carefully.
Regards
