Hi, the same happens to me when a filter or special view is applied (which is also sensible, since you can't be sure you are viewing the correct next segment).

Hi Brian, are you working with a pre-segmented file? In that case, it's not (and it shouldn't be) possible to change the segmentation by joining/splitting

Hi I am using V3.2.11. When I try to join 2 segments the "join segments" option is greyed out. Why is this? Brian

Hi, just as the glitch came, it went. I didn't start or close any special applications, simply rebooted the computer. thanks Istvan for your support through
