Another alternative for the xyz positions is to use the NIS element user log in. This way the xyz positions are saved for each user and do not show up in the other users' account.

I also tell users not to tick in the 'move stage to xy position' as this easily leads to accidentally moving the stage. Instead we found that if you double click in the x or y columns, the stage moves there anyway even if the 'move stage' box is unticked. Single click simply selects the line so that it can be edited. Accidents are less likely to happen if one needs to double click.

Med vänlig hälsning / Best regards
