Zooming Level problem

Hello all,

I have a zoom problem. Once when I worked in a document I
upped the zoom level to 150%. Now every time I open the
document (and any other document there after) they open up
in 150% zoom, when I'm used to only working in 75%.

I've changed my normal.dot - have worked in a document at
75% zoom and saved it, but still my problem opening
documents at 150% zoom exists!

Any help, as ever would be much appreciated.

Cheers



Greg
