Hi guys very occasionally (it happened twice today but hasn't happened for some time) when I first boot up my computer I get a prompt pop up I think it has Error on it and it says "Can't find a suitable pixel format" I click OK and my computer seems to work OK

but it just happened again and I clicked OK and I then moved my mouse over the red F@H icon in my task bar to see how it was doing and the icon disappeared and I had to restart F@H so I guess this might be a F@H problem.
I think when I have had this problem before it has been with an earlier F@H install so I guess it must be a bug in the program. Has anyone else had this problem? It's no great hassle as it only happens very occasionally.
