Hi,
Which version of IE you are using?
I suggest resetting IE or running IE as Administrator. (Right click IE shortcut and choose run as administrator)
If you are using IE9,
please check if the following blog is helpful.

For IE9, you can click the compatibility view icon beside the address bar or switch to basic html view to standard view in Gmail.
Best Regards,
Niki
