Have just updated GM with the latest build (b081915). I have exported part of an existing ECW image but when i open the new image exported image in GM it does not display but it exists in the Overlay Control Centre. Is this a new bug in the latest release?

    I recommend that you send a detailed description of your workflow and results, along with your data, if possible, to Blue Marble Geographics Support (geohelp@bluemarblegeo.com).  This will ensure that the support team knows about the problem, and will expedite a solution.  Thank you.

     It looks like there's a bug in the 'export raster' dialog for ECW - enabling the "Include Projection/Datum in Header" checkbox adds a 4th (alpha) band, which makes the whole image fully transparent.
    Solution: Unchecking the "Include Projection/Datum in Header" solves the issue, and does not affect the inclusion of proj/datum in exported files - everything then gets exported as it should.

    Thanks for the answer, will make sure the Header box is unchecked from now on. Keep up the good work...cheers
