Gnuplot console window doesn't open when script is called

Question

I have a problem with gnuplot 5.2 patchlevel 8 (but previous patchlevels had the same issue) on Windows 10: When executing a script file (from the explorer by double-clickung on the .plt file), the plot window opens, but I cannot get the console window to open (as it used to do with space bar on 4.6). I'm using the wxt terminal, but it's the same with qt. Is there a way to get the console window?

Bonus question: In case there is an error in the script, how do I get gnuplot to open the console window and siplay the error message instead of immedately shutting down again?

how do you execute your script? From the Windows Command prompt? — theozh

If you are double clicking on the file and gnuplot starts, then Windows has some association with this filetype to open these files. I don't know what this is in your case. Maybe gnuplot.exe?

Why not starting wgnuplot.exe to open the gnuplot console and typing load "myScript.gp" or eventually using the full path of your script? And if you modified something in your script press the "Arrow-up-key" and "Enter" and run the script again.

What you can find in the manual on page 45:

If gnuplot was built with configuration option -enable-raise-console, then typing in the plot window raises gnuplot's command window.

Apparently, your and my version were not built with this option.

(a) The .pltextension is associated with wgnuplot.exe.(B) Of course I can start gnuplot directly, but then I have to manually change the directory.

well, but this means if you build it yourself you can include this option ;-)

Windows gnuplot installer associates .gp, .gpl and .plt with wgnuplot.exe. Double clicking a script file (bearing one of these extensions) does call wgnuplot and draws the plot, however, the wgnuplots console does not open.
