I use the attached file: ex-IBM-2004-09.gdt. It then generated an error (as shown below) when I tried to have a time-series plot with any variables in that file.

I tried other "daily data" like djclose.gdt but no such error.

This error can be replicated in gretl 1.9.12 and 1.9.12cvs.

I just tried the version of 1.9.11 (under winXP). It seemed OK with the same time series plotting.

Thanks
