Hello,
The 'Import from text (CSV)' function in v4 has a strange behaviour (it was perfect in previous versions) : fields become agglomerated, or left blank, whatever is the separating character !
I found a solution : copy/paste the text (with TABs as separators) in an Excel sheet, then import it by the 'Import from Microsoft Excel' function. It runs good, but it adds automatically a blank entry in the database (i.e. if you import 5 lines, you get your 5 lines plus 1 blank line)...
