WPFFontCache_v0400.exe Is Hogging CPU

Hello Sir,
i have installed Visual Studio Beta 2 Ultimate on my system, Windows XP 32 Bit, 1 GB RAM, Intel Processor etc.

the installation of beta 2 goes successfully.

i can open the IDE Easily.

but after creating/opening a project, my system becomes very slow, i thought that devenv.exe is taking a lot of memory and CPU, but when i opened Task Manager, i saw this WPFFontCache_v0400.exe taking 100 % CPU and close to 3 MB of memory.
It is showing my CPU Usage to 100 % all the time, this exe is running.

now my question is that why this exe is hogging my CPU.

Kindly please help me in this.

Looking for favorable replies.

Thanks
