Thanks for the example script. Here's a standalone version which doesn't
require other files on disk:
<hansl>
open denmark
store check1.gretl
store check2.gretl
loop i = 1..2
open "check$i.gretl" # also tried without quotes
endloop
</hansl>
This indeed sends the latest snapshot (on Win 10) into a non-responsive
state for me, the OS being needed to shut gretl down.
This sort of thing cannot work.
The non-responsiveness is now "fixed" in git and snapshots, in that an
attempt to open a session file within a loop produces an error
message. Besides using the GUI proper, you can open a session file via
command in the console, or at the top level of a script, but not in a
loop. By design, opening a session file clears out then repopulates
gretl's entire workspace, and doing so within a loop is bound to
destroy the integrity of the loop itself: after the first iteration
the loop-counter variable will have disappeared.
