It does oviously not depend on the Mach version, and I could not do a clean install yet, or vary my other circumstances.
Here is my current screen set (attached), and it refers to the plain MillBitmaps. Maybe the screen set contents makes the difference. Can you try it, please, Hood?
Maybe soft limits on A are handled by the driver... there is another option, M5 macro command that works only with the driver.
I'm running on a Windows 8 32 bit, on a virtual computer, and I doesn't install the driver. I do have the option of a virtual Windows 7 32 bit. The host is a Windows 8 / Windows 8.1 64 bit Intel i7.
