Not that, but a platform dependency nonetheless ;)

It turns out that for Windows, string data placed on the clipboard in 
the standard format must end with a null terminator. In other words, for 
  a string like "foo" we actually want to store 4 bytes (where the last 
byte is zero). In contrast, X expects just the string data without the 
null terminator (e.g. just 3 bytes for "foo").

So a workaround for that previous example I sent you is to replace this 
line in the SEL_CLIPBOARD_REQUEST handler:

   @treelist.setDNDData(FROM_CLIPBOARD
                        FXWindow.stringType,
                        currentItemText)

with something like:

   if /mswin/ =~ PLATFORM
     @treelist.setDNDData(FROM_CLIPBOARD
                          FXWindow.stringType,
                          currentItemText + "\0")
   else
     @treelist.setDNDData(FROM_CLIPBOARD
                          FXWindow.stringType,
                          currentItemText)
   end

but I will try to come up with a more palatable solution for the next 
release. Maybe the best thing is to add a pair of module methods, like 
the existing fxencodeColorData() and fxdecodeColorData(), for working 
with strings going to or coming from the clipboard.

Hope this helps,
