Is this also a problem with 1.92?

I will try 1.92 but the problem appears to be with the .js files in the script directory and as far as I can see those files have not changed in 1.92.
Specifically modaldialog.js and uploader.js

Tmac: I just checkeded this on 1.92+ and it works fine. Can you please check it too and tell us if it works?

I will check that as soon as the comfort update is available. Will get back to you.
(Its just a time thing to do the manual upgrade, will wait a few days)

OK I have installed 1.92+ and have tried to populate a dummy survey with answers and images. Same thing, I can get the images uploaded but if I try to replace one of them by deleting and uploading another, it fails on the next upload and gets stuck.

Here is a link to see what I mean (expires next 23rd March)

The above applies to new images loaded into a new survey.

I now have new problem though maybe unrelated. The existing database/survey contains references to images in json format (as expected) but 1.92+ seems to have a problem reading the old json text from the database fields.
For eg. If I use mysql to examine the json field (image title, comment etc) it looks ok. If I then attempt to update a response with the survey form and get to the image loading question, it does not show the old image, instead just a garbled json code with 'format errors' and then without saving/submitting, if I look as the database field, the old json text is gone and replaced with <span=

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&amp;id=7991

1.92+ update released.
