Adv Radio Group Async Problems

Saga continues with the component TIWADVradiogroup.

 
I am trying to set the item index of one radio group back to 0, or anything else in another radio group's asyncChange event.
No Go .
Are there still ASYNC issues in 4.5 with radio groups?
Are other controls equally ASYNC-Challenged?

Please post this to an IntraWeb related NG.
