problem with questionnaire filling

Dear everyone,

I have been using LS for 2 years and now I have a never seen problem.

If I send an invitation for somebody and he starts filling the questionnaire the answers upload and saved. If he takes a break into the filling I send to him a re-invitation. His answered were saved and he could continue where he stopped.

Until now. Because now the welcome message appears again and he has to click the 'next' button. (although his answers appear in the boxes, and I see them in LS)

I don't know what happened but it is not good for me. I don't want to show the welcome message if he started to fill the questionnaire.

Is there someone with similar experience or solution?

Thanks,
Bogi
