DOCUMENT:Q195854 01-MAR-2002 [sms] TITLE :SMS: Poor Mouse Control Using Cirrus-Logic 5436/34 w/ WUSER32 PRODUCT :Microsoft Systems Management Server PROD/VER::1.2 SP3,1.2 SP4 OPER/SYS: KEYWORDS:kbsms120 kbsms120bug ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Systems Management Server versions 1.2 SP3, 1.2 SP4 ------------------------------------------------------------------------------- SYMPTOMS ======== When you attempt to take Remote Control of a Compaq Deskpro 2000 computer with the Cirrus Logic 5436/5434 chipset, you will see mouse hesitations. The severity of this problem increases with the increase in the amount of colors being displayed. For example, the mouse hesitation is a problem with 256 colors, but the mouse is virtually unusable when you are showing 65536 colors. This problem occurs regardless of the driver version loaded on the computer. CAUSE ===== Capturing the screen image using BitBlt can take a substantial amount of time, and no mouse movement can be processed while the capture is happening. The jerky mouse movement increases with the screen resolution because Systems Management Server captures a 256 color image of the screen, so screen resolutions other than 256 colors must go through a color translation step that can take a considerable amount of time. WORKAROUND ========== To work around this problem, use a faster video card or a faster processor. STATUS ====== Microsoft has confirmed this to be a problem in Systems Management Server version 1.2 Service Pack 3 and Service Pack 4. The third-party products discussed here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
