I am using Version 1.91+ Build 120302 of limesurvey. The survey asks users to upload a minimum of 3 image files associated with a question.
The survey is set as 'persistent' so users can update responses later.
After uploading 3 pictures successfully, I then try to delete a picture and replace it with another (as would a user).
At that stage if you upload the image, limesurvey says max files have been uploaded (as expected) and also says, you can return to the survey.
BUT - The return to survey button does nothing, the pop-up java dialog remains on the screen. If you close the dialog is just comes back, you cannot exit.
So in short, if you upload 3 pics and continue, everything works as expected.
In you delete one or more of the pics and replace them, you get to upload the pics but you can not return to the survey and save/submit it.
Let me know if you need more info, I would appreciate your help.
