Attempting to view Channels in Prefs 'errors'

Opening Panorama X Preferences, then clicking on the Channels tab results in ‘Cannot set parameter 3 value.’

Side question: Can the forum be searched for an exact match of words? I’d like to search the forum for ‘Cannot set parameter’ but I get many results that do not contain that set of words in that order.

Enclose your inquiry string with quotes to get an exact match of the entire phrase.
