Copying Objects between different version of RunRev

[Dave]

Hi,

It is possible to copy and paste objects (like fields, buttons etc.)  
between different versions of RunRev? E.g. I have a stack open in  
RunRev 2.6.6.152 and empty Stack Open in 2.7.4.291. I select and copy  
a field in 2.6.6 then click in the 2.7.4 window and attempt to paste.  
Nothing happens! It is supposed to? If not, why not?

All the Best
Dave
