two monitors have same camera view

Asked by paul zimmer on 2012-10-28

when i create the first monitor in zoneminder it works correctly. when i add a second monitor, both monitors show the same camera view. i can change the port on either monitor and the camera view may change but both monitors have the same view. this is true if i create all four monitors. it looks like both monitors are assigned the same pid. please advise on what system information is needed to examine this problem.
using a quad core cpu 4gb memory with card 105 (provideo pv143) on ubuntu 12.04 and zoneminder 1.25
