I'm trying to get a new lathe working but I keep running into this issue. 

Whenever I run anything from MDI or G Code, Mach Control is delayed for something like 6 seconds before I can do anything again.  This is the first time I've ever had this issue.

I thought it may have been the additional scripts I added in, so I removed the CustomFunctions Module I made, and removed any custom scripts from the Screen Load and PLC scripts.  Still had the issue. 

Thought is may just be the lathe profile so I ran the unmolested Mach4Mill Profile.  Same issue.

I unistalled Mach4 altogether.  Same issue, mill and lathe.

Any Ideas?

This must have been a processor issue.  I changed to a new (new) computer and the problem is gone.

If you would, attach the exact screen (not one with the same name, I mean the exact screen) you were using when you saw this problem. I would like to look at something and will possibly have a fix for you to try.

Brett,
Here is the exact Screen I was using.  Although, I will say again, this was happening off the stock Mill and Lathe Screens as well.
Windows 7 Professional 64 Bit

Thanks.

No problem, keep in mind though, default screens get updates sometimes too.  

I would be interested in knowing if you see any improvement using the screen I'm attaching to this reply.

Attachment removed.

Brett,
The computer I was using is now being used for our shops PA system (break bells, time to go home bells, etc.)  But it still has the Mach stuff on there.  When I was having issues before, it didn't matter if I was using the SIM or if I was using the HiCON as my motion controller. 
Two weird things happened. 
1.  Now, since I don't have the HiCON on this computer anymore, I ran the SIM.  It works just fine on the Original Screen that I gave you.  Annoying.
2.  Your C8-2.set isn't allowing me to use Cycle Start, Feedhold, or Stop.

Thanks Chad. Just trash that screen I posted. Sounds like the issue is with the plugin and the changes I made to the screen only introduced other issues.
