Reading Inputs

There seems to be a little snaffoo with reading inputs. My home inputs work fine for all six axis I'm using, but this code hangs:

Code "g91g00 z-.52"
SystemWaitFor(18)
Code "g04 p2."
Code "g91g00 z.5"

signal 18 is for Input 1 which shows on the screen just fine, but when I try to trigger something by it, it does nothing. I've tried reversing the "Active Low" check with no difference in results. Maybe this isn't functional yet? Let me know, and I can work around it.

#2
I'm homing only X,Y,B,C. The X and Y automatically ZERO, while the B and C don't, in fact won't. When I try to change the DRO for the B and C, it reverts back to the previous numbers when I ENTER. The only way I can get those two axis to cooperate is to exit the program then restart. At this point it will allow me to change the #'s to ZERO. Any Ideas?
