It shouldn't cause any issues. I would just ignore it and use it. The form's doublebuffered setting deals with some display issues, if true it might (note the word "might") slow down the display a little for a really complex form, but otherwise it resolves several problems with display. With modern computers the speed issue is mostly non-existent unless a form is really complex. I am not sure why Mervyn added that init method bit to set the doublebuffered property, except perhaps if you are using the preview.wfm file with a version of dBASE before that property was added (I can't remember now which version it was added in).
