DOCUMENT:Q102131 29-JUL-1993 [W_NT] TITLE :Mouse Leaves Trails; Standard VGA After Warm Boot PRODUCT :Windows NT PROD/VER:3.10 OPER/SYS:WINDOWS KEYWORDS: ---------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT operating system, version 3.1 - Microsoft Windows NT Advanced Server, version 3.1 ---------------------------------------------------------------------- SYMPTOMS ======== If you have a VESA local bus video adapter with the Cirrus 5426 chip set, the following two problems may occur: - On a fast VESA local bus machine, pixels are inappropriately left on. For example, moving the mouse pointer leaves a trail of pixels. - After a warm boot, the standard VGA driver (640 x 480 with 16 colors) is run. CAUSE ===== Inappropriate pixel activation is caused by the speed of the machine. This problem also occurs under Windows 3.1 with the same hardware configuration. The warm boot problem is caused by a timing conflict and does not occur on all configurations. RESOLUTION ========== For the pixel problem you need to either slow down the processor speed of your machine or obtain a new video adapter. If you cold boot your machine, the video driver problem does not occur.
