Hi. If you're using opera 12.** then you should use some addon like AntiBrowsniffer.
Or change the browser signature by right clicking in the site then "site preferences-network" and trying to select Internet Explorer or other variants.

Sorry my bad English

is there a way to make opera default browser?
