I am having a reoccurring problem when modifying or using Mach2.  My
computer freezes and I have to reboot, this is happening when I am
using Mach2.  This is usually happening when I am modifying settings,
sometimes it also occurs when I am in idle mode meaning no activity
other than Mach2 running.  Am I doing something wrong in terms of
setup of my computer and Windows.  Why is this happening?  Any help
would be appreciated.

The version of Mach2 is 6.11d.
Machine is Techno Isel Model 27


Thanks,

Thanks for the help.  One of those settings must have solved my problem.
I will see if this problem reoccurs again.

Thank you,
