Question about markers, please

Hello again, and thanks for reading this. I'm having a little problem with getting my project to stop and return to the beginning or wherever I ask it to return to. Here's what I mean:
I have always used Reason and Sonar together in the past. Whenever I wanted to set a return point in the song, I just dragged the "R" marker in Reason to wherever I want it. That's all it took. Sonar always followed along with this. But, since I upgraded recently to newer versions of both products, ( now using Reason 7 with Sonar x3 ), I can't get the song, or project, to stop at the "R" marker. Anything that I have done in Sonar along these lines, has failed also. In Sonar, I have gone to "Options" and then checked everything there in some configuration or another in order to get the song to return.
Since I have always used the Reason way of getting the project to return, I'm afraid I am not very skilled at trying to get Sonar to make the song return.
I do not expect anyone here to be a Reason user also like I am, but I know that there are some mighty sharp people on this forum who may know this. I hope so anyway.
The reason I don't go to the Reason forum for this is because it seems to have just sort of fallen away over there. Pity.
 
In case you do know Reason, here is what I have done:
 
Dragged the "R" marker to wherever I wanted it.
Selected the "Loop" button
Punched in the numbers of the project to correspond the way I wanted them
Done what I already mentioned in Sonar under "Options"
 
None of these things cause any change to occur at all in regard to stopping or returning the project. 
 
Sure wish I could get this simple matter solved and I hope someone here can help.
 
Thanks for your time and consideration

I use Reason 7 also.
 
You are doing everything right.
Problem is your perspective.
In a ReWire setup REASON is the SLAVE.
 
Any changes to the loop setting/timeline/etc.
MUST be made in Sonar AND ENABLED  if
you expect the changes to happen.
 
REASON will let you change loop points if loop is ON in Sonar,
and start and stop(press numberpad 0 twice to return to zero in Reason);
Most other stuff you have to Reference
from Sonar(e.g. hit w on the keyboard to return to zero).
 
Hope this helps,
Mel
