Hi Joss – I sometimes use a stylus – I’m into photography and digital drawing/ painting – so if the stylus is in my hand I use it – I have checked this and it dosnt seem to be a factor – it happens with or without and also dosnt happen with or without – currently I am trying to keep tabs on what I have done directly before typing a post – but can’t as yet find any correlation – happy to post other things I have ruled out if this helps ?
