I don't know anything about the StarSQL driver, but I have seen similar issues using DTS against ODBC (specifically Firebird). Sometimes it seemed to work and sometimes it didn't, but mostly it didn't and I wasn't ever able to figure out how I got it to work the 1 or 2 times it did come through. I resigned myself to either having a printed copy of the model nearby or having one tool up on one monitor and the other in a 2nd.
