One of the issues you and others may have run into is the latency  
occurring between use of the TextEdit scrap and synchronization with  
the desk scrap, i.e. the clipboard.  Prior to Carbon, developers were  
instructed to synchronize the two scraps on layer switch -- when an  
application became or ceased to be frontmost.  The problem with this  
approach is that it doesn't play well with screen-in-a-window  
arrangements where switching to another app in OS X doesn't cause an  
OS 9 layer switch and consequently gets stale clipboard data.

I've written a system extension called TESyncScrap that patches TECut 
() and TECopy() to flush the TE scrap and TEPaste() to update it.  I  
invite you to try it out and see if it's useful.  The source code is  
also available.[1]

You'll need a MacBinary decoder.  There are several in the  
'experimental' directory.
