Updated via GUI just fine. No apparent overload Avast servers that are handling the GUI update

Regarding Avast 6.x, WMP11 XP color problem.
With all due respect to those still using XP, franking it is an outdated operating system regardless of which SP version you are on.
In fact when you have the SP3 release installed you have so many fixes from the original release of XP that by laws of programing you are almost guaranteed to run into problems especially when using the the latest releases of Security software.
Now some may have no problems and that is great luck. Good for them
My recommendation to all Windows OS users except for application testers is to upgrade to W7 SP1.
Windows does have a WMP12 but it will not run on XP, unless there is a hacked version of WMP12 out there that will.
The majority of computer users will save themselves a lot of computer related grief by installing W7 SP1.
The added cost will more than pay for itself in the time and headaches saved by continuing to use XP whose kernal is now about a decade old.
