Form received by email is viewed not as designed?

[Steve]

Hi,

I'm new to info path and have created a form to suit our business, as a test
i've sent the form to my own machine and it comes out perfectly well, however
sent to another machine on our internal network (other machine being a mac
and mine being pc) the form is all over the place?

Another problem with the form which i'd like to get right is the whole form
with our logo at the top is positioned centered but when received via email
the form is viewed to the left and the logo centred?

Help with this will be much appreciated, perhaps i could even email the form
to you.

Thanks

Steve
