We make a commercial asp.net app and try to support the widest range of browsers possible.
Telerik seems to have no solution for some of them, workarounds for others.
Chrome and IE and FireFox aren't having these same problems, I'm wondering if we should just say Opera is unsupported and call it a day on that since it appears that Telerik is unable to support some of their stuff on Opera and don't seem to test other stuff at all on Opera because some of the issues were pretty obvious right off the bat (transparent background in context menus etc).
Do you support Opera or just call it unsupported?
