John, Thanks for your advice on ATI. So far it hasn't caused me a lot of trouble. Note that I did find a workable solution to the conflict. Thanks again, Greg

I found a solution to this problem already, with help from my MCam vendor. Am posting to provide my solution to others. When I clicked [Macro] Record, mouse pointer disappears. Mouse is still active and clicks do select controls. I cannot get mouse pointer visible again until I exit MCam. Problem exists in X4 MU3 and X2 MR2. The following did NOT help: [*]Updated video driver (ATI Radeon X300/X550/X1050 Series) [*]Also tried all combinations (on/off) of the following settings (rebooting where appropriate). [*]X4 Disable Hardware acceleration [*]X4 Disable front buffer [*]ATI Control Panel OpenGL Triple Buffering Finally isolated the problem to UltraVNC (Ultr@VNC) ptional video driver. It seemsthat the “Winvnc video hook driver” (note that it can appear as other names in the Device Manager) is the problem. Here’s a description from http://forum.ultravnc.info/viewtopic.php?t=3258 that describes the driver. What is it ? The Mirror Video Driver is a driver that UltraVNC (for instance) can use to be quickly and efficiently notified with screen changes. Using it on an UltraVNC server results in a excellent accuracy. The video driver also makes a direct link between the video driver frammebuffer memory and UltraWinVNC server. Using the framebuffer directly eliminates the use of the CPU for intensive screen blitting, resulting in a big speed boost and very low CPU load. It seems understandable from this description that the symptoms I experienced could appear. Either disabling or removing the driver (a Start menu shortcut dedicated to this task is provided by UltraVNC) solves the problem. I did the latter. I can still use UltraVNC, but with slightly lower performance. FYI – I use UltraVNC to remote control the Router I post my MasterCAM output to.

Thanks! This helped me. Error occurred with McamX4 on my WinXP system. As advertised, the McamX4 parameters in the registry were still set to X3 paths that were deleted by uninstall. I fixed them myself (not for everyone to try at home). X4 MU3, Router Level 1

Art demos also available on your hard drive after MR2 install. Look in mcamxdocumentation I think. Very informative.
