Only one grib channel shown

Thanks for your reply with general advice. But I have used this combination (Xygrib+BSH) before and then it was not a problem. When switching to ch. 2 only (Xygrib) nothing is shown. On ch. 3 (BSH) or all only the currents are shown (which was loaded before Xygrib). Unfortunately, screenshots were not accepted even though they were jpg files < 90 kb. Concerning the "grib with best resolution" I understood that that only concerns grib files with the same type of data. But there is not current in Xygrib and no wind data in the BSH current files...

Are you sure that in grib display settings you asked for both wind and currents data (for instance first arrow->wind and second arrow->currents ?
I can assure you that there is no problem with all this here and that nothing has changed in this area for ages.
Eventually send your 2 gribs to support@meltemus.com and I will have a look

OK, it was the grib display settings where the current map disappeared from the secondary arrows. Now it works.
