Yep, that's about right. There are quite a few commands which, for one reason or another, don't work on locked buffers.

Quite sure its been discussed before but it was probably three or more years ago.

From the manual :o)

DrawRect / all draw commands can, depending on the driver, refuse to operate on the buffer. This issue is especially known for NVIDIA cards

Well, the manual says they don't work, so i reckon you should probably take that as a no-no ;o)
