Hi Emma,
It is best to create a small sample publication that replicates your problem. You can upload the IMP file to this forum in its native IMP format, or zip it up as a ZIP file if the publication is large or has to have resources. When you are using the forum, you will need to "log in" if you wish to have file attaches seen.
When you have typed out your message ready to post here, you will note the Preview and Submit buttons. You should also see an Attachment button, click on it and it will then let you upload your file.
RE: your Page fade transitions and Resizing problem....
Please have a look at the attached IMP I have mocked up for you. Both features are working, so check it compared to what you have done.
Hope this helps!
