PDF overlay does not show

In version 13 and 12 I have the following problem/bug.

I have one .pdf file with a ~4.5 m pixel size in NAD27 Geographic NAD27 projection, a .tiff file with ~9 m pixel size and a .tiff file with a ~4.5 m pixel size, both in UTM WGS84 projection. If I start GM and open the workspace everything comes in fine. If I unload the workspace and then reopen the workspace the overlay based on the .pdf file does not show. The control center shows it, but it does not display.

These files total over 300 MB so I can't easily upload them to you so that you can verify this behavior.

I can work around this, but it should probably be fixed.

Thanks in advance,

    More than likely you are running out of memory rendering the huge PDF file multiple times inside the PDF library that we use. We have a new 64-bit build of Global Mapper that can now support PDF files that might get around the issue. If you have 64-bit Windows try downloading and installing from the link below and using it:

    64-bit: http://www.globalmapper.com/global_mapper13_setup_64bit.exe

    Let me know if I can be of further assistance.
