I was wondering if the new libndofdev specified to be available in JIRA issue:
https://jira.secondlife.com/browse/STORM-312 could be integrated in to Cool VL Viewer. My understanding is that the 3rd party lib has been updated to handle EL_ABS events which newer kernels use for the Space Navigator. Right now my Navigator is not functional with SL and Cool VL viewers and I really dislike keyboard navigation along with an essentially dead input device sitting on my desk.
