[GRASS-user] copy paste in command window

Hi,
When I paste a command in the command window it writes it down twice.

For example, I copy
“r.in.srtm input=N31W082.hgt output=srtm_test”
and when I paste it I obtain:
“r.in.srtm input=N31W082.hgt output=srtm_testr.in.srtm input=N31W082.hgt output=srtm_test”

Why is that? How can I change that?

Thank you.
