i have this issue with most of the robot i worked on. I installed on each robot the version GripperSpotTech (188.8.131.52). It works perfectly when i pres the deadman button, but sometimes the menu in the bottom left that i can use for opening or closing my gripper became non selectionable (like i'm not pressing deadman button). If i want to reabilites it ,i must select a random program of mine and it works again. This doesn't make sense for me. I don't know if i explained it well. Any ideas?
