Hi,
my problem is that if I select whole text line and try to copy it and paste to notepad (or back to the same SMath sheet) I get only part of selected text.

Steps to reproduce:
1. open new worksheet
2. input this text:

Citazione

a el(Re.a,1,1):{nthroot(Re/b,3)+sqrt(3.6)}/sin(3)/{4^{2-o}}}

- as there is a space as second char, this is treated as text region (alternatively one can use Insert->Text region and then insert this text or similar).

Then double click on inserted text. All text is selected. Then copy (^C) and paste it (^V). Only part of text is copied. Attached sample file.

Just paste and manage the disposition.
