CCXML is not recognized in Windows 7 in setting Default/Active

Hello,

I normally have more than one CCXML file stored in different projects, I then do right-pick one and set Default/Active

Now I start using Windows 7 and this feature is intermittent, sometime I've seen this option on CCXML file, sometime NOT, ie I've seen the same option for CCXML file as other file.

I'm using CCS-5.2

Is it a bug ?

Thanks,
