I very much doubt that will help.
I have the same problem at the same time as the last update. WGT broke something for us and they dont know what.
For your info here is what I have tried and all to no avail. For more info tell us which keyboard you are using it may help narrow it down but I doubt it.
Logitech G15 keyboard, removed reinstalled drivers . Still broken
Reinstalled Maxthon browser . Still broken
Use Google chrome browser. Still broken
Use IE 11 and Edge browser. Still broken.
Use Torch browser. Still broken
Use my old Microsoft internet PS2 keyboard. Still broken.
Come on WGT sort this out it has to be something to do with the last update, One of the admins should have to spend a day not using his spacebar and see how frustrating this is.
Any more ideas folks ? I am at a loss.
