[Gretl-users] bugs in gretl 1.9.5cvs

I have detect the following bugs in bugs in Gretl 1.9.5cvs: 1) with some data (for example attached data), the ADF test doesn't allow the option "quadratic trend", but includes it in the other options. 2) If I select an AR model with specific lag and conditional ML, I can't remove the AR selections in the other ARMA model in the session. Is there a way to bypass these problems?
