switchfilter does not work in 3.2.3

Question

I have installed the motion 3.2.3 and found that switchfilter on (or 1 or yes) does not detect any motion though the CHANGELOG file shows that this bug was fixed. With switchfilter off motion works though I'm having problems where images from one camera are sometimes beeing mixed with ones from another cameras. I reinstalled motion 3.1.19 and found that the problem occurs also(with the same config file)

part of motion.conf

Answer

Try 3.2.4_snap2 MotionRelease3x2x4snap2

I found an old bug recently and the feature may work better now.
