I don't think the problem is in the lab, but in plot.  If you just run

   plot i. 5
   plot 1 3 2 5 4

You'll see that the display is not immediately updated, but requires some event to make a paint happen.

The solution could be to change to an isidraw control, or to force glpaint'' at the end of graphics.

I am fearless and will try to change anything, but I would like to give someone who knows the plot package better a chance first.

I rarely run labs. Would you fix it by yourself? Thanks.
