OK, I'm going to say it..... Bob I think your wrong! It's more like 99%.

I have been working with the folks at Maxim on the issue. Playing around with the problem, I can now reproduce it at will. Bob might have given me an upgrade, but I aint no genius, once the problem was reproduced, it's clearly a harware/driver issue.

John, I also have a SSAG. Now that HF 8a addresses the 8 bit guider (great timmig Bob), and Maxim 5.04 addresses the calibration issue, I think I've found my solution.
Now on to learning User Commands.... OH Yeay!!
Thanks everyone. Paul
