Certain tiff images do not appear

Hi there, wonder if anyone has had a similar prob to what
I am currently experiencing?

The problem has occured since the upgrade to 10.3, with a
certain file that was created on 10.2. Some of the
images (not all) do not appear anymore, interestingly if
I open the file from a 10.2 machine all is well! It
seems to be more with tiff images, if inserted as a jpg
they appear fine.

Anyone experience the same problem?

Also, occasionally when inserting a picture from file,
powerpoint closes, anyone seen this?

The machine is a new Alu PowerBook 15" with 10.3.2 and
all microsoft patches are applied.

Any help would be greatly appreciated!

Jay
