Dave Smith Instruments SYNTHESIZERS

Hey, thought id also post these concerns about the PC editor here, 
ive sent these to sound tower, but havent recieved explanations.

Can anyone else confirm these problems , or explain how to acomplish 
these tasks?

......................................................................
 How can i make Ctrl+C  Ctrl+V work to copy and paste patches? The 
edit menu  lists this shorcut, but it doesnt seem to work. Just plays 
notes.
 
Why does the right clicking "copy" not include patch changes, while 
the edit  menu copy does? This is strange and confusing. Should at 
least have a  different name. Like "Copy with Updates" or somthing.

   How can i save patches once pasted in the Library, i only 
see "save as" to create a new bank, how do I save to the existing 
banks? Why do I notget a "Save  Changes?" prompt when closing the 
program with newly created patches ive  placed in the library , but 
apparently have notbeen saved?This was a pretty frustrating discovery 
after creating 5 new patches,only  to reopen the progam the next day 
and find them gone. And again,how am i  even suppose to save them to 
the existing banks in the library?

Im also noticing that the Rename function doesnt work for renaming 
patches in the library, from both the right click and edit menu.Am i 
dong somthing wrong?

still hoping to hear some explanation soon,,,
