New laptop - Very strange keyboard issue when using other languages

Hi,

I'm currently on holiday in Thailand and I bought a basic laptop for writing while here. It's an Acer Switch One SW1-011 with a removable keyboard. It's running Windows 10 32-bit single language and everything is in English. I added Norwegian keyboard to English US as most of what I write is in Norwegian. On a Norwegian keyboard, there will be a character known as ø where the semicolon is on other keyboards. I have several laptops and PCs at home with both English and Norwegian keyboards, so I know my way around them. The issue I'm having is that the ø character does not type when I press the key for it (; semicolon). However, if I hold the key down, suddenly several øøøøø will start to appear. So I have to do this and delete the extra ones every single time I want to write an ø. If I change the language to Eng with international keyboard, the semicolon ; (same key) types just fine. I did an experiment and added a Danish keyboard, which has the ø and æ characters reversed with respect to Norwegian keyboards and the same thing happens, only this time it's the æ that will not type unless I hold down the key. So there is something strange with this one key and languages other than English and it is driving me crazy trying to figure out how to fix it!!! Can anyone help? I downloaded SharpKeys and AutoHotKey, but they aren't helping.
