(...)

My second question is that once those 100 variables have been selected and gretl asks for confirmation of deletion, the list of
to be deleted variables goes beyond the right edge of the screen and I need to move the window to the left few times before the "OK"
button becomes visible. Is this something that occurs on my system or is it a normal behaviour of gretl?

Dear Sergei, this is the normal behaviour (I get it using Gretl for Mac OS/X and Windows Vista). But in my humble opinion I think it would be good if we have a more compact window (with more than one line).

Best regards,
Henrique
