Rename Patch Point problems...

Anybody got problems trying renaming patch points with Sonar Platinum Kingstone Update 1 (but even with older versions was the same!)?
Simply don't work at all,and after you rename a patch point the name changes only in the receiving track,the sending track remains with the original name (patch point 1) and if you create a send to send the sound to a receiving track you can't delete no more that send after you have created,you click "delete" but the send remains on the track!Weird!Some times (with complex projects) Sonar hangs totally when you try to rename a patch point!
I got that behaviours since the first implementation of the patch point routing,not only with latest updates,im the only one?
 
 
 

The name of the source track is not intended to change. The name shown in the Output (or a send) will change. I'm not seeing a problem on choosing Delete Send. By design, the patch point remains in existence until no other track is using it, either as input or output, but the send is removed as intended. I've not seen hanging when renaming.
