Umlauts not correct

Re: Problem typing Umlauts with United States International keyboard.

I am using Opera under Windows 10 with United States International keyboard. In all other applications, in order to generate an Umlaut, I type "Quotation Mark" followed by the vowel in question, resulting in ä, ö, or ü. Doing this in Opera the result is ""ä. ""ö or ""ü. Please fix this. It's very annoying. The problem only exists in Opera, in no other application

I should add that I have the problems I described earlier ONLY with Opera. I have no such problem with any other program

I am typing mostly English texts, on a QWERTY keyboard, but also occasionally German and French - and there the United States International keyboard settings seem to be the most convenient.

My keyboard/language settings are "US International" -- and it does not work. If I hit the Quotation marks key it type two quotation marks"". And If I want to type U Umlaut I get two quotation marks and then U ""U

Can't find opera://flags/#experimental-start-page
Still I would like to set my speed dial icons to reload periodically as they used to do in the past.
