Hi Slava,

Instead of simply pasting the text into LiveCode, do the following:

set the unicodeText of fld x to the clipboarddata["unicode"]

Now you can do this:

on mouseDown
  select the clickText
  set the unicodeText of fld 2 to the unicodeText of the selection
end mouseDown

or whatever you would like to do with the clickText. This works fine on Intel processors, I'm not sure wha happens if you try this on a PPC processor.
