Notebook issue

Formatted notebook with graphs were saved in a packaged Igor file in a PC (Windows, Igor 6.20). The graphs would be gray boxes without any curves if the file is opened in a Mac (Igor pro 6.12). Is this caused by different operation platforms or different versions of Igor Pro?
Your graphs have been pasted into your notebook in a Windows-only format. The only viable cross-platform format is PNG, a bitmap format. You can convert all the pictures in a notebook to PNG by selecting all the test (Ctrl-A) then select Notebook->Special->Convert to PNG.
