I upgraded to 7.17 last week and duely paid the $20 but ever since I have had a problem with mirc whereby previous lines in the window I'm chatting in will go black (seemingly random) and things that were typed hours ago will appear to be the most recent - completely mixing up conversations and even swapping them to another room if I'm in 2 or more.
I have tried uninstalling mirc and, although it might work fine for a while, the blackout happens again. Also, the minimise etc buttons in the top-right of the toolbar also black-out although they do function with guesswork.
No-one else I know that uses mirc has a solution to this so any advice would be appreciated.
