I have downloaded 30 US TOPO GeoPDF's from the USGS website and have tried to load them into GlobalMapper 12. The 64 bit version will not load them at all and the 32 bit version will load all of them but will only display 12 of them. I can unload some of the ones that are being displayed and then load some others, but it will never display more than 12.

    This is because we don't currently have a 64-bit version of the 3rd-party PDF library that we use and also that PDF files are loaded entirely into memory, so you are limited as to how many you can load in the 32-bit version. What I would suggest is using the File->Batch Convert/Reproject menu command to batch convert them to another format, like GeoTIFF, then just load those files directly where you shouldn't run into the same limitations.

    Let me know if I can be of further assistance.
