Hi Katherine,
Glad you got it working and yes you can be sure that even sighted users can get confused in sql server management studio especially if they are new to it and just learning.
I'm not sure if there is a specific forum at Microsoft for questions about accessibility but with just a brief search I found this site which is about accessibility in Microsoft products (though it seems mostly about consumer products not developer tools):
http://www.microsoft.com/enable/
I also found a Microsoft site that is for helping developers to make sure they are developing accessible applications.
http://msdn.microsoft.com/en-us/windows/bb735024.aspx
I noticed in the Videos section on that page an interesting series of 5 videos about how to develop a screen reader. I'm sure it is a simple one not as advanced as Jaws, but interesting to note that one could build a screen reader from scratch.
Maybe if you dig around on those sites you will find forums as well. You can be sure that my certifications give me no special access to anyone at Microsoft. I do know a few people there but Microsoft is a huge company and just knowing a few people doesn't give me a direct line to the top or a louder voice or anything like that.
Best,
Joe
