Ok, having a really annoying problem, I'm having to type this from Notepad and then copy and paste. This surface pro 4 and pro 4 Type Cover work fine for everything except this website?? I get about 3-4 word in and then get massive lag, like it takes 5 or 6 seconds for the word 'the' to appear and the 't' was missing. Then after that only a fe letter apear for each word with long pauses between the random letter. It's basically unusable. Quickly tried Edge search window and Chrome and they seem fine. Is there a setting I need to switch on or off?
