DrawState redraw.htm - Check to turn off
If you manually set this (the middle of the 9 small checkboxes) , the system will turn on another pseudo "auto-redraw" feature that, even though it is somewhat slower (or faster depending on your point of view), will produce a PULSE or flicker effect showing each and every print that is made to the screen.
Any information written as such will be erased whenever another window apears in front. This produces an interesting latent effect when the dimension of the erasure is next visited. Otherwise the screen only refreshes after all the grid features have been plotted, and because the "Shortest Path" lines are drawn at the end of each bandpass, when you have selected a large DrawWidth some labels will be enhanced by this bandpass filter or obscured.
WARNING: - Persons with a known history of epilepsy should be careful using these accelerating displays.
Another way to uncover these labels is to uncheck the Mode
& Style selector
to temporarily disable the DrawWidth (Mode) selector.
