I created the online game from Flava's article and everything works fine, except the Text Blitter. The Text Blitter shows the player names above the players and it does but when the player moves up or right it draws black lines on the screen of the other players.
(On screen i started 2 apps on my pc, but i also get this problem when trying it on 2 pc's.)
Oh and the movement engine from the article doesn't seem to work properly, the player doesn't stop on obstacles.
I'm guessing, for your purposes, that you don't want the Text Blitter to be displayed as a background? Because if that option's checked, there appears to be no problem...
But if you need if active (to show up over other active objects), there are ways to get around the scrolling-pasting bit. You make a second Text Blitter object, resize it to be the size of the screen, and keep it always centered as the screen scrolls. It doesn't need to have anything displayed in it, it doesn't need to be over or beneath the other Text Blitter(s) (I think), and it shouldn't cause any noticeable speed drop (as it doesn't have to test for collision). But it should prevent the other Text Blitters from making a mess.
