Problem with ă, â, î since the "new look" update

[odt5]

Ever since the update that gave us the current look and layout of lessons, I've been having an annoying problem: if I type in an answer that ends in ă, â, or î, this character disappears/is erased when I press "enter" to submit the answer, which of course often leads to incorrect answers.

For example, if I type in the correct answer "Mașina ta e frumoasă", when I hit enter it becomes "Mașina ta e frumoas" which is of course incorrect.

I'm using Opera browser on Windows 10. Has anyone else gotten this problem, or can anyone let me know how to fix it?

Thanks
