Hi, There appears to be a strange error related to the function package GUI in *Package: yahoo_get 3.9 (2026-01-20)* for *gretl 2026a*. When I run the following script, everything works correctly: nulldata 1000 setobs 5 2022-06-01 # a daily dataset should already be in place delete index series apple = yahoo_price("aapl") # get Apple, adjusted price only list L = yahoo_full("msft")

However, when I access the same functionality through the GUI (as shown in the attached file), I receive the error message: *"Argument 1 (ticker) is missing."*

I'm not seeing this problem on a recent snapshot from March 25th on Windows. Don't know if there was a recent fix in that area affecting yahoo_get, but from the changelog it's not apparent. cheers sven _______________________________________________ Gretl-devel mailing list -- gretl-devel(a)gretlml.univpm.it To unsubscribe send an email to gretl-devel-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-devel.gretlml.univpm.it/

Hi, Thanks for quick reply. 😀 I conducted further investigation into this issue and found that the error message, *"Argument 1 (ticker) is missing,"* persists in installations from *gretl-2026a-32.exe* and *gretl-2026a-win32.zip*. However, the error does not occur in *gretl-2026a-64.exe*. Could this issue possibly be related to the 32-bit (win32) version only?

The 32-bit build of gretl for Windows uses GTK2, while all our other builds now use GTK3. In late 2025 we added some "remedial" code for GTK2, intended to emulate functionality that is provided natively by GTK3. Apparently there's a bug in that code, whereby it "loses" the ticker string argument for yahoo_get. A fix should be forthcoming before long.
