Crashing when removing pages

[treeclimber]

It doesn't appear that I can rearrange pages in my 60 page book I've been working on for several months. So I reluctantly decided to add pages and copy and paste text for the many I need to move around. And then delete the original page location. I can easily add new pages where I want them but every time I "remove page" it crashes. I deleted all the text and tried to remove it that way ("remove page" and "remove all blank pages") and it crashes that way, too.
HELP!

Hi Treeclimber -

Please ensure you are running the latest build of BookMaker 2.1, available off our website 2.1 build 1971. My other recommendation is to not cut and paste text from any other external application other than BookMaker. Sometimes, without realizing, cut and paste text can stick in characters that are not recognized by BookMaker. From time to time, this can cause issues.

Sincerely,
MyPublisher
