Hi Stoyo,
Is there a way to disable repainting while performing changes in the chart?
i.e if I have to perform a long series of programmatic operation on a flowchart, e.g. adding boxes and arrows, moving  them in proper position, resizing document, panning and zooming... I don't wont to see the boxes continuosly moving aroung the screen : could it be good while running in debug environment, but is too time spending and not good to see while running in production environment.

I try to set Flowchart.Visible:= False before starting the series of operation and reset Visible := True at the end, more or less seems to work, but this cause the flowchart to be unselected and this is somewhat undesired.

an example: I use the Mouse wheel to zoom in and out.
when I make a zoomin I perform several panning and zooming operation; if I set visible /not visible the flow chart, the mouse loose the selection with flowchart, so the next onmousewheel  will no more be fired.....

so :Is there another way to disable repainting ( like a Disablepaint property?)

Thank you
Franco
