Internet Explorer Compatibility Mode

I have recently found that when I log into SnippetMaster, I am unable to select from the styles menu in the WYSIWYG Editor window. I have also found that I am unable to select a ‘class’ for an image that I added to a page. I am using Internet Explorer 10. I have checked the page on several different browsers and have not found this issue. It appears to be something to do with Internet Explorer. When I check the ‘Compatibility Mode’ button, the page refreshed and throws me back to the login screen. When I login again I am able to select the styles menu, and classes when adding images etc.

Is there a way to force IE to use Compatibility Mode when accessing on a new computer, or do I need to manually enable it each time?

Many Thanks
Very Happy
