During last several months we got multiple complaints from users that Image Uploader had problems with GUI in Firefox and Chrome under Mac OS X. We were not the only one company having these troubles with Java applets on Apple platform, there were a lot of posts on Mozilla and Apple forums from developers about that.
Since we have Apple Developer account we tried to contact Apple about this issue, they confirmed it but didn't reveal any time frames on resolving the problem.
Several weeks ago Apple released Java 18.104.22.168, this version works both in Mac OS X 10.6 (Snow Leopard) and 10.7 (Lion). Preparing new Image Uploader 7.0.35 for release, we invested significant time for testing this Java with our product under both versions of Apple operating systems. The results are much, much better. The applet works perfectly under Max OS X 10.6 and 10.7 in Safari, Firefox, and Chrome. The only limitation that we found is no drag and drop support in Firefox/Chrome under 10.6 and in Safari/Firefox/Chrome under 10.7. All other functionality works perfectly in Image Uploader 7.0.35 and Java 22.214.171.124.
