There is a website that I use to upload photos. It uses the Silverlight plugin. It seems to work sometimes and not work other times. I had issues in the past and then I found it working one day (Safari). I haven't used it to update photos in awhile. I tried today but can't get it to work again. I select the photos that I want to upload and get a ! message. I did some searching and found that I can go into Preferences then to Security. I selected the option to always trust the site that I upload the photos to. That didn't work. I tried in Chrome but get this message when I try to install Silverlight there - You can’t open the application “Silverlight (4).exe” because Microsoft Windows applications are not supported on OS X. Also tried Firefox with no luck. Any suggestions?
