Albert, I am not quite following what you did. Did you highlight 50 symbols and hit CTRL+H? what did you do exactly. I don't really understand exactly what the issue is
As far as closing, I need to get the log file to see what the problem is. Please do the following:
go to FILE / Export/Backup menu (from Dashboard or Portfolio) Select “To share with others” export file protection option on top right Leave the checkboxes already checked, and also check LOG FILE. Export, then email me the exported file please.
