Hi.
I have tried to hook up my pokeys board to do some testing with Mach3.
When I program as an example pin 1 for x axis (left arrow or right arrow) and do a send to device, if I click on the menu at the top of mach3 screen, each menu start to open from left to right on a non stop way.
On the window screen, if I double click on a icon, instead of opening the software, it act as I right click and got the property window.
I tried with a NO switch and a NC switch and it does the same thing.
If I try without opening Mach3, it affect the computer and have to press reset or disconnect the pokey board to get control of my computer.
