S
I tried win10 and hit a few problems.
I could get into the subject section of a PM but not get into the message part of the PM.
On another occasion I lost a complete post when I hit the cursor key, so re-typed it in word and tried to paste it into the post, but it said my browser (edge) did not support copy and paste, I then emailed the copied text to myself,copied it from the email and when I pasted it into the post it converted to a page of symbols. I then went onto a win7 machine and pasted from the email into the post with no issues.
Thanks Chris
