Are there any know issues with the use of raise/lower preset in conditional statements for RF keypads in HWI 1.65? I have the exact same functionality working on a wired and phantom keypads without any issues. The RF subsystem stops talking with the main process after executing a raise or lower preset in a conditional statement (key pad LED's waterfall after executing). The RF keypad doesn't appear to be an issue. I get the same result on all RF keypads in system and they work great for any other programming action or mode. I can cause the same system crash by simulating a keypad press, release or hold sending by keypad command from the terminal window . I tried moving the raise into the conditional press action, but had the same result, RF hung and no longer to communicate with system, H8P5-H48-120. Funny thing, the terminal continues to see keypad button pushes and releases, even though the RF keypad can't see processor (waterfall LEDs). See hold picture for command that is crashing P5. Thanks in advance for any help. -joe
