I am evaluating Mach4 on , my windows 10 pro laptop and seem to have a problem of Mach4 locking up and freezing at times, I'm pretty sure its not a problem with my laptop as it is very powerful and can handle memory intensive programs with ease, I do not have a machine connected to the laptop and my router is running Mach3 on another win xp computer, I'm just wondering if all will be ok if I run Mach4 on my win xp computer before I buy a license.
