Thanks for looking into the problem. I'm sorry that you were unable to recreate it on your end. I checked every single page of my WP Dashboard and all are displaying as I remember them before I installed your plugin. Unfortunately, there isn't an error icon displayed either. And, to make troubleshooting even harder, I am using the exact same vesion of IE 8 you mentioned testing (8.0.7600.16385). Perhaps it is a conflict with one of my other plugins?
I am using:
AddToAny: Share/Bookmark/Email Buttons - Version .184.108.40.206
Akismet - Version 2.5.3
All in One SEO Pack - Version 220.127.116.11
FT Signature Manager - Version 1.3
JPF Register - Version 1.0
leenk.me - Version 18.104.22.168
Maintenance Mode - Version 5.4
SABRE - Version 1.2.0
Subscribe2 - Version 6.4
WP-o-Matic - Version 1.0RC4-6
Any known conflicts with what I've got?
