No, not here. I'm still displaying my "Known Issue" message.

For what it is worth, I just doubled checked and I found this to be true: on the same machine (Server 2003 w/ SQL Server 2005 Express SP1), I have two DotNetNuke 4.x installations:

DotNetNuke 4.3.3, Forum Module 3.20.08
"My Posts" Error (ORDER BY items must appear in the select list if SELECT DISTINCT is specified. 0)

DotNetNuke 4.0.3, Forum Module 3.20.06
"My Posts" OK

[a little later...]

(on the same machine as above) I fired-up a third DNN 4.3.3 installation, with included Forum Module 3.20.08 and confirmed the error: ORDER BY items must appear in the select list if SELECT DISTINCT is specified. 0

Then... I removed the Forum Module 3.20.08, and installed the Forum Module 3.20.06 and confirmed: "My Posts" OK - error gone.

Thanks, Alex - for getting it logged.  After re-reading your earlier posts in this thread, I see how for you the error happens in either DotNetNuke 4.0.3 or 4.3.x, and with either Forum Module 3.20.06 or .08 too.  For me, I could localize the error to Forum Module 3.20.08 - but either way and both especially - it's an issue worth resolution.

For the fix, I will be happy to run any tests/trials since I now have a couple of (new/clean) DNN installations built specifically to try to localize this problem.
