I'm not sure what you mean by crawling lines, but if you're referring to the 'marching ants' whenever you use selection tools, you can change the appearance in Edit>Preferences>Image Windows and set the speed to 2000-2500 ms. The selection line (so called marching ants) will now be motionless and change only every 2-2.5 seconds. It is pointless though to completely get rid of them, since when you make a selection you have to be able to see what you'd selected. Nevertheless, you can do it in Menu bar>View and uncheck Show Selection or just hit Ctrl+T.
