Okay, I know there aren't that many people using a Mac in the MS Expression Web forum but there are a few who are using Expression Web using Parallels, VMware Fusion or Bootcamp, and there certainly must be a fair number of Mac users in the Expression Media section since it is the only program in the suite that comes in a Mac native version but there really is no excuse for tread previewing not to work in Safari.
Like most good front-end web developers and designer I test my sites on the major browsers on both a Mac and a PC. I'm sitting here typing on my MacBook and went to check this forum only to discover that the thread preview arrow doesn't work in Safari.
Come on Microsoft, as the company that sells one of the most popular applications for the Mac (Office for Mac) doesn't make their forum software fully Mac compatible, especially when one of the programs the forum supports is a Mac native program? Especially, when the primary selling point of Expression Web and Silverlight is that they are cross platform web standard.
While you are at it how about:
Improving the speed of the forum?
Fixing login issues, where you type a reply hit submit and get logged out (okay it is only occasionally but it should never happen.)
Add the ability to do everything in the Ajax preview/reply that you can do if you open separate threads to reply.
Fix the "notify" option so it actually notifies you to changes to the thread selected AND doesn't cause the submit button to fail 50% of the time.
Speaking of submit button failures when notify of changes is selected, why does that cause the post to appear not to post or even throw an error that says it was not submitted yet result in multiple posts of the same response?
I could go on about the problems with the Expression Web forums but I think I'll stop now beyond asking why in the world Microsoft changed the url so that it now starts with "social" http://social.expression.microsoft.com:80/Forums/en-US/web/threads/
When I want to be social I call friends, go out to dance, to a pub, to dinner, out for a spin on my Vespa or if I want to be social on the web I'll go over to Twitter [http://twitter.com/cdwise] or Facebook or one of the other social networks and check in with friends across the net. I won't go to a technical forum, sigh.
Update: after running software update on my MacBook the dropdowns are now working. I also cleared my browser cache. Worder if this is another Forum-javascript-cacke issue or if the probelm will depend on which version of Safari you are running on your Mac?
