Do I have a bad blitter chip, or > is the problem systemic with all Mega's? Yes, i had the same problem. Dragging a window very fast from left to right and back left a lot of vetical lines on the screen. I think it has something to do with the accessories you have installed. When i used ALARMCLK and some ramdisk, the problem occured. Now i have a different configuration and i have never seen these symptoms again. I have a Mega ST4 & SH205 and now with the following Programs in exact this order in the AUTO-folder: ETERNL3 TURBODOS FOLDERxxx IDLE12 Acessories: Mouse Speed (Speed up the Mouse) Extras (new File Selector Box) ROCP MemFile! (1.4) I hope this will be of some help. Werner XBR3D815 @ DDATHD21.BITNET
