SOLVED
the problem was (and probably has nothing to do with the 1903 update) that i had switched on 'Show text suggestions as I type' on the hardware keyboard setting (Settings -> Devices -> Typing)
i checked settings with my 2nd pc that was working all along and voila!
hope it helps someone
Hello there
Just installed windows 10 May update (ver 1903) and i have problems using the keyboard/chat in l2 classic
I cant input chat or keyboard commands (shortcuts for the game etc)
The workaround i have found is to change focus (click on desktop) and the keyboard resumes working for a while...
Thanks
PS my 2nd pc seems to be ok so .... weird ...
