Good point.  The dialog box should be modal though...let me think about 
that one.

I'll try, but it is random and the usual info seems to somewhere other 
than the terminal window.

Yes.

Oh man, operator error!  I didn't even know such a setting existed in 
the wxt terminal.

Well, guess I'm OK with the existence of such a setting in the terminal 
window, except for the fact that there seems to be a logical conundrum 
to it with regard to a command-line persist setting.  That is, right now 
if one launches with:

gnuplot -persist

and then looks at the wxT terminal settings, the "Don't quit until all 
windows are closed (persist)" is not checked.  Shouldn't that be checked 
if "persist" actually is active?  But if that box were forced to be 
checked, it would mean that the next time gnuplot is launched wxT would 
be persistent regardless of the presence of "-persist".

Furthermore, if launching in "-persist" mode, opening the settings 
window of wxT and checking and then unchecking "Don't quit until all 
windows are closed (persist)" takes the terminal out of persist mode, 
obviating the "-persist" argument.

If the terminal is to have control of this (why it should, I'm not 
sure), then maybe there really should be a third "setting", or 
non-setting, i.e., make the checkbox non-checkable or grayed out or 
something similar.  That is, launching with "-persist" might make it so 
that the checkbox in the wxT terminal settings is gray and can't be altered.
