Looks like you've turned down your display resolution to mininum, or messed up your video driver. Not sure about W7 as I don't use it, but you could try (this is Win XP method) right-click desktop / properties / settings and then setting the resolution higher. If it's your driver then it's going to be a bit more hassle.
as per the advice given on the FB page, by elsadog, As I believe this was a result of something else that went wrong System Restore it does as it says on the tin
The thing did it for me, Just checked Compatibility then it said error and found one that worked! It also could have been switching from Fox which had been very dodgy recently to Chrome which as my computer running like a dream!

Out of interest what setting in compatibility did you change and to what?
