Ok. I was reacting to your comment "Why doesn't publisher 2010 allow you to just copy an entire page..." and of course it does and how to do that was explained earlier...that is why I suggested you weren't reading very carefully.
Your issue is different. You are having problems with the formatting changing when you do copy and paste a whole page or even single text boxes onto a blank page in another publication. That is an issue others are having and I don't have a good solution.
I personally can't replicate it.
In the recent thread: http://answers.microsoft.com/en-us/office/forum/office_2010-office_other/when-i-try-to-copy-paste-a-page-from-one-publisher/b7ed907f-bac9-43f1-a526-bccc45378cd1 Mary Sauer suggested:
A workaround:
Change your printer settings to Publisher Imagewriter on both publications before you copy/paste. For some reason, I have yet to figure out, it seems doing this the formatting doesn't change. At least it didn't for me. "
Otherwise you might try the 'format painter' which at least could potentially save you time reformating the text boxes.
Publisher has been the poor neglected step child ever since it was adopted into the Office family in Office 2002. It has never been given the same amount of resources or attention and really lost out in Pub 2010 in my opinion. Even the ribbon they finally
forced upon us is not the same as in the main Office programs including PowerPoint. The word art is not the same, the pdf tool is not the same, they are deprecating the web building functionality and more...but that is the way it is. Personally I don't see
Pub 2010 as much of an upgrade, but then I hate the ribbon and resent that it has been forced upon us....done with that rant.
As I suggested above please make your suggestions to MS and perhaps if enough people do then you will see some of these improvements in the future:
