Carl and all,I think I know what's going on. It's not really a true fullscreen, because the window title bar and the taskbar are visible. I believe this is Scaled Mode (activated thru a menu or with RightControl-C, AKA Host-C) with XyWrite fullscreen. I can achieve something similar in Ubuntu; see Fullscreen-Xy4-in-VBox-Scaled-mode.jpg. True fullscreen mode (RightControl-F, AKA Host-F) produces a dismal XyWrite with ALT-Enter, see Fullscreen-Xy4-in-VBox-Fullscreen-mode.jpg.On 07/28/2014 04:14 PM, Carl Distefano wrote:Bill:If you can achieve fullscreen, which is what you want, that's OK, but you should find it easy to make any VM (that is, W2K and higher) any size you want.Makes sense; I need to play with that. After I discovered full screen, though, I was also somehow able to make windowed XyWrite bigger. I must say that, although I'm elated about getting full screen, I'm nervous about the fact that I don't quite know *how* I got it, other than at some point hitting Alt-Enter. One of the side effects of doing so was to change the resolution of the virtual Win 7 desktop from whatever it was down to 800x600. This appears to be related, and may even be a sine qua non, for getting a full-screen DOS session. It's a little disconcerting because all of this happened without my consciously changing any settings. I'd really like to identify the necessary steps and settings so that I can replicate it on other machines. A quick search of the VirtualBox user forums did not provide much enlightenment. It seems that other people have stumbled on this phenomenon, but so far I haven't found a step-by-step procedure for achieving it. And I confess I haven't yet cracked the VBox documentation.No, when I experienced the lag, it was about the same in a window and full screen. But the lag substantially disappeared in both window and full screen after I rebooted the VM. And I've rebooted the VM several times since then, and the lag has not come back. When I'm typing in full-screen, I can barely tell the difference from Xy running full-screen under WinXP.Does lag decrease in fullscreen?Attachment: Fullscreen-Xy4-in-VBox-Fullscreen-mode.jpg
