Ignore Limits option grayed out

Ignore Limits option grayed out was created by Aciera
My mill uses compressed air to compensate the weight of the z-axis. After shutdown the Z-axis sits on the Limit-Home switch an I used to check the "Ignore Limits" in the jogging screen to move the axis off the switch. Now for some reason (and after quite a bit of changing other stuff in the HAL and INI) I can't check the box as it is grayed out.
Is there a setting somewhere concerning the "Ignore Limits" checkbox being active or not?
Thanks

Thanks for your reply.
When I try to start the machine with F2 there is a message saying the machine cannot be started because an end switch is active. I'll try to get a screen shot next time I'm in the shop.

So here we are:
The machine sits on the Z-Limit/Home switch and I cant start the machine (F2). The errors are:
"Error: Joint 2 on limit switch"
"ERROR: Can't start machine. Is there a limit switch active?"
So I have to change the HAL and set the display to "axis", comment out the gmoccapy-postgui.hal and restart LinuxCNC with axis screen and I can check the "Ignore Limits" checkbox and move the axis oft the limit switch.
Why is this not possible in my gmoccapy? This used to work (I think).

Solved.
In gmoccapy as opposed to axis I have to go into E-Stop an out again for the "Ignore Limits" checkbox to become available.

My mill does this, but I don't have this problem.
I think that if you activate "HOME_IGNORE_LIMITS" on the INI then the problem might go away.
(Though thinking further, it shouldn't. I will try to look in more detail at the behaviour of my machine this evening)

@Aceira,
what release of gmoccapy do you use? See title bar or setting page.
In 3.0.8 I do not have that Behavior.

Thanks Norbert for your reply. I'm still on 1.5.9!
So I guess I'll see about updating...

I'm not sure if this would work, but I wonder if you could and2 the limit switch with the is-homing signal for that axis? That would allow you to jog off the switch before you home. That might not be quite the right signal but it might be worth exploring options like this might yield a solution.
