When I run that report out of Matrix Plus the report looks differently or does not run at all. Search your hard-drive for the crpe.dll file. Generally you will find two copies of this file. Check the versions of these files. I type in notes on my registration screen and they don't show-up anywhere else.
Matrix allows different versions of sample notes to be kept.
This is controlled by the options on the notes push button. Check the note buttons to ensure they all have the same number stored in the options portion of the notes push button. My Save All button within the dialog editor does not work. Edit your EditDialogList screen and make sure the list box displaying all your screens is set to be a single select, sorted box. Select multiple samples at a time on your sample selector screen before going into the result entry by sample screen.
