mayor drop refuses to work, wont build tavern

so i have this new settlers quest - level 3... ! but i cannot drag settlers over mayor

the mayor does NOT light up. there is no icon of an item being dragged .. nothing.. i cant just click the mayor after in case the icon is invisible - no response

then i get to the next drag quest - stones, pinewood etc.. and i cannot drop that either ??

this is me hovering over mayor holding "10 settlers" -- but as you can see - there are no icons .. etc.. mayor is not glowing.. it gets marginally brighter only https://prnt.sc/12zsrw0

i get a quest to build a tavern - there again is no building icon - nothing to drop .. and again clicking any green space doesnt build .. the interaction just cancels.

https://prnt.sc/12zrzn2
(in the pic you can see the cancel button - but no item to build).

font scaling only applies to chat?? not to mayor tabs or email or?? anything else?? please return browser scaling which Works on everything!


thanks

opera version is 76.0.4017.107 on win 10 (frankly the game will not open in any other browser i tried - ff, edge, chrome, slimjet - all cleared cache b4 tried)
