cut, copy paste do not work with selection

[Jordi Castells <jorcas69 telefonica net>]

I am using gnumeric 1.1.20 from ximian desktop instalation

I try the following:
- edit a cell with F2
- select a part 
- copy it with CTRL+C
- go to another cell
- edit it and paste with CTRL+V

the result is all the previos cell is copied instead the selected part

cut has a silimar behaviour, all the previus cell is deleted and copied
in the new one

what is wrong?

regards
