But isn't that user's rights to choose whether to open save or run. It would be great if one can predefine in browser's options what to do with certain type of files. Of course if Opera developers want to play everyday user friendly stuff, its ok to predefine certain browsers actions as "save all in d-folder", but why to deny change options?
For me it was: first I was angry that I couldn't open these files, then I was forced to dig in options and didn't find anything, then I wasted my time to search in net to finaly find out that there is no such option at all.

And that's the problem - you still need to make extra clicks. You may call me lazy, but isn't that the idea to make all faster and more simple?

BTW and how about such simple thing as click on torrent download start file? Instead on opening with onPC download software Opera now saves this (in other way useless) file and user must click on it to open it with, for example, μTorrent. There is no problem to clear download folder from these files, but, in first place, problem is that user must click many times to start download process. It's ok if you need only one file to download, but if you have 50 different seperate files? You need to click to download and then find them in download folder and click again to start download process.
