I cannot confirm this running in German with "almost-2021a" (snapshot
Jan 14th),

Hi Sven, I'm on the 2021a version

checking in the console. Or do you mean the CLI program
directly in the shell?

Oops, I'm a little bit confused now with the termikology ...probably you're right: the CLI in the Shell (well, the windows titre is "gretl console")

However, after testing around a little bit I realized that it doesn't happen always:

1) probably it happens when more then 11 variables are involved.

2) the summary command needs to be the first command in a new "console" window

Hope it helps,

Best,

Artur
