It's funny that in the old Google Docs I was able to upload documents with no issues in any browser/OS, but it seems that in Drive I cannot do it using Opera on Linux (but I can using Chrome). Also, the way in which shared documents have been handled in the transition is just plain stupid.

I never find it strange when Opera doesn't work. It's not Opera's fault, web developers generally don't care about it.
