gnuplot will not load a ".plt" file in "windows explorer" with a "search" parm. I beleive that the "dir path" goes bad. Can load & exec file if no "search" ; if search then flicker and "nada".
I think the path to the current file is not read , and the gnuplot fails to load the data.
Yes, if you put
into your script (instead of an actual plot command), you see that windows actually executes the script in C:\Windows\System32 instead of the current path if you run it from the search window. (tested in win7 here)
I guess you will have to work around that, because this is a windows feature, not a gnuplot bug.
Unless there is a special windows configuration option for that, which the gnuplot installer should set ... ?
