<p> <i>I fixed the focus problem by changed the window property to floating.=A0</i><p> That's not a good fix - although the focus quits flashing, the windows don't - you can't control the Z-order (who's in front). Overlap the windows and see.
The occurrences simply controlled the launching of the windows, not the distribution of data. Once a window was opened, the occurrence played no part until that window was closed and opened again. The key factor was that the code in each window was running at the same time as all other windows. Your scheme still has the window display new data and stop. Therefore you're tied to the fact that the parent has execution most of the time.
