I run W2k sp4 with an ATI x800 xt, and I get a blank white window at 4.8.1 startup, and then another blank, slightly larger greyed window opens titled "language options". If I move the grey window over so i can see the white window, and then hold the mouse button down over the grey window's title bar, I can see a moving action bar that says "loading HTML engine". Releasing the mouse button makes the action bar go away. Nothing else happens; all i can do is click on the "X" box to close the grey window, then both the white and grey blank windows close. 4.8.1 needs a fix,but dont know what. Support says ATI cards can give problems, but if older versions of LW worked, why cant they fix the bug in this one??
