Global Mapper v24.1

Global Mapper 16.2 (latest download) : "Error C++ error embedding overlay <filename> Exception: Bad

curtcarto Global Mapper User
Have a National Hydrography Dataset that I'm working on. It's been simplified in GM. And now I'm "sorting" it by creating a field, to which I put an "x" on the 'good' rivers I want to show. So I select, edit the field, add the attribute, then continue.

That's been working for awhile. But now if I have the workspace open for awhile, I get an error when trying to save the workspace. The layer (a shape file) exports out to a new .shp just fine. But again, after working for awhile, I get the error message:

"The following error were encountered saving the workspace:
Error C++ error embedding overlay <filename> Exception: Bad Allocation"

The shape file is not open anywhere else. The PC that GM is running is freshly rebooted. New machine, plenty of RAM, etc.

Anybody help me out?

    I recommend that you contact Blue Marble Geographics Support directly by sending a e-mail to  Please include a detailed description of your workflow, and the error message you are getting.  The support team will have a better idea whether or not anyone else has reported this same problem, and if we have a fix available.

    Hi Bob,

    Yup, already sent them the same thing. It seems to be with the one large .shp file. It's a slightly modified version of the NHD Plus file for the Lower 48 states. Seems like a memory issue.
