Add DP +clear = crash

Bug report

Hog III console V2.2.2 (1809)
2 external monitors
1 DP

New Show
setup>patch
@
select the add dp text
set
clear


dialog box says "Invalid set number" followed shortly by a console crash, all screens dark. Touch screen pointer still follows, but trackball and all front panel controls are dead. Pig+Open+Backspace does nothing. Must pull power and wait for battery to die to reset.

On a side note, is there a way to remove a DP from a show?
