Hi Paul,
not saving the "Options -> Memory & Threads -> Parallel Threads" is probably on purpose. When saving it in the Prefs and migrating everything (including the Prefs) to another computer, you may end up with poor performance because of an improper value.
Also, it's all too easy to forget setting it properly after changing it for some tests...
If you want to have a certain non-default value, why not put it into the StartupMacros.txt? You can do the same also for other options that you always want to initialize to the same value, e.g.:
macro "AutoRun" {
// reset options
run("Colors...", "foreground=black background=white selection=orange");
run("Options...", "iterations=1 pad edm=Overwrite count=1");
run("Profile Plot Options...", "draw interpolate sub-pixel");
run("Memory & Threads...", "parallel=1 keep run");
}
Michael
