I'm getting strange delays when I do things in Word. It takes 5/6 seconds to bold some text or display a blank print-preview, that kind of thing.

I've noticed it only pauses the first time you do something e.g. I load up Word, type some words, bold a word *wait 6 seconds*, bold another word and it will work instantly. During the delay it's not hitting the HDD or CD - it just sits there - almost like it's loading something into cache - but what!?

Is anyone else experiencing this weirdness?

Laptop specs are below. Also, it's 64-bit but Word is installed in Program Files (x86). Don't know if that's relevant.
