I noticed a major issue with the AjaxUploader. It works fine when my page first loads however as soon as I open any modal window (I use modal windows on the same page for selecting people to email and so on...), the uploader will then no longer open. The icon no longer works and if I tab to it and hit the space bar it says file browsing has been blocked.
this only occurs in Firefox which all my users use. Email me at
[email protected] and I will forward a link you can test.
