--- Comment #7 from jpsollie janpieter.sollie@kabelmail.de --- I do not know yet where the error is coming from, but this may give the developers a hint:
On my report (https://bugs.winehq.org/show_bug.cgi?id=49185), i had the same problem.
Because I could not find a solution, I booted into win2k19 and ran the respondus browser from there.
When I used language "ENG/US" and keyboard layout "Belgian Azerty", the issue was exactly the same compared to wine staging. When I used language English/Belgium and keyboard "Belgian Azerty", the issue was gone! So I don't know whether this will be of any help, but I hope it does
