This has only just happened within the past week.
It is only certain programs that won't open such as Itunes, Paint Shop Pro, Photoshop & Windows Media PLayer. Those are the only ones i've discovered so far.
The onyl way i can get these programs to open is by going to say for itunes, and mp3 right clicking and going to open with...
Double clicking the program won't work either.
I'd usually do a ghost but my floppy disc isn't working atm and system restore isn't working either.
Any ideas anyone?
