@Derbys29 and @Soprano91396 The error when working with lists or clicking on people in the side list and using the chevron next to move forward or backwards usually won’t occur until after quite a while
Try reading this thread ( start at top as Jerry gives a very detailed explanation) and see if this is what is happening to you as this will occur in a very short time – I could make the error occur in 3 to 8 clicks
Please let us know if this is what happening-- IF NOT then please tell us exactly the steps you take before the error occurs…
