This might sound an old question but I was stuck on this for quite a while. I can't maximize report preview window via the KEYBOARD '{CTRL+F10}'. Tried running my report on both VFP6 and 7 and it still didn't work. As an alternative, I just define a window and maximize it and it worked. But I'm still wondering why the KEYBOARD '{CTRL+F10}' is not working.. Any idea?
