Posted all of this into feedback tracker now.
I have also logged out, logged back in and unticked remember me.
I then logged out again and logged back in and ticked the remember me button.
Finally I closed my browser down without logging out and then reopened the forum and went to feedback tracker to test if it was still going to open with wanting me to login and still refusing me.
But now it works. Have tried closing without logging out and reopening a few times and it is all working fine now.
Looks like something wrong on my computer so don't expect the developers will be able to replicate the problem. As a developer I know it is next to impossible to answer or correct an issue in that case.
so pthhhhhhhh. forget my comments on this. Just the other one with iClone not recognising folder shortcuts anymore after updating to 7.21. As said it used to work with 7.2 so I don't think that is related to something with my computer?  At least I hope not.

I am so busy working on a project and have no time for all these darn bugs....wo so many, too many to list. 1 example is that a video back shows through all models and characters, How in the heck is that even possible? Anyway, I need back my IC 7.2 now (it worked fine) so I can get this work done...I am on a deadline. How can I do this? quickly....I am waiting.

The only way to roll back is to remove 7.21 from your system and then run the 7.2 installer that you have hopefully saved on an external drive.

I'll put this in the Feedback Tracker, but here is a video showing effects of viewport size on overlapping opacity textures, in this case the Daz hair.
The vids are not identical, I used a different lighting for the one I got working. 
And you would say, "Well, then just make it mini...", right?  But, when you do, lighting you will experience a loss of lighting fidelity (becomes pixelated with artifacts).

Anyway, thx to 4U2Ges for past suggestion, and enjoy!

I've found another issue with 7.21 and reported on feedback tracker. In the timeline there is supposed to be a morph track available for props that have morphs created in the morph editor. There isnt  an option to select such a track.

Gaaaahhh!!!!   It angers and offends me that the preview window has any effect on the render results!!!!

If I was the product manager, I'd lock all the develoopers in the building until it gets fixed.  I'd buy Mt. Dew, Monster drinks, and pizza, but nobody goes home until something that dumb is solved.  Gaaaahhhh!!!!!!

My screen shots were taken just before I made my post, and are from 7.21.

I can't add any more information as to why your system isn't showing the tracks correctly. It would be interesting to know if other users are having this issue or not, unfortunately there are only a few users who take time to reply to such posts.
