start at top, the timeline is downwards.
3 weeks behind thanks to central heating debacle so need to catch up with work backlog, so I dont have time just now to try for a normal working time on a file and study it by the minute for when it happens, and also keep doing screen captures at every stage of the workflow, as not started my days work yet through other things going wrong here, to replicate if it happens with layer palette turned off and on, it did it as can be seen with closure of rhino. thats for sure.
V4 never did it, V5 does it. V4 and V5 on tower and laptop. tower win7, lappy xp.
Will do this test on lappy when get time.
