Hi Brent,
I tested with your code under Firefox 2.0012, IE6 and IE7(your browser I believe).
In all three browsers, the pin icon was visible and
RadSlidingPane4 could be easily closed without issues.
I will therefore have to request that you open a new support ticket and attach a sample
running app reproducing this exact problem in IE so we can help you solve the problem.
Your help is much appreciated in preparing the app and we look forward to hearing from you.
Best Regards,
