Hi Rick,
Thanks for all the screenshots! @designsimply and I worked together today and we were able to test in IE9 and confirm the problem. It's a pretty strange bug!
Any idea how long it will be before the bug is fixed? I'm just curious--I'm not going to hold you to anything. ;o)
We've reported the bug to our theme team. The theme team reviews bugs every week, but how long it takes to fix each one will depend on how many are ahead of you, what other issues are going on in theme support, and how much time is available to spend on bugs that are only happening in some cases. So, I couldn't really give a specific time frame, but I can tell you that bugs do get reviewed on a regular basis.
Now we'll just need to wait for a reply from the theme team as soon as they have a chance to look at this issue.
Thanks again for all of your patience with this and for working with us on those screenshots! WordPress.com has the best customers!! :)
