Update:

I can of course make this work by grabbing the relevant portion of screen (rather than specifying the field):

  put globalloc (Topleft of field fname) into tl
  put globalloc (botright of field fname) into br
  export snapshot from rect tl,br to file imgPath as PNG

But this is a bit risky as I can't guarantee that there will be nothing on top of the field (e.g. floating palette) or that the field will completely contained on screen.

Hello everyone.

Can anybody help with this ...

I am exporting PNGs from fields, using this syntax:

  export snapshot from field fname to file imgPath as PNG

This works just fine on about 30 or so fields, but when I come to one particular field it fails with error message:

    export: can't write to file, mask file, or container

All the fields are opaque. If I switch this field to non-opaque... it works fine... or if I export as JPEG it works fine! The only difference (that I can see) between this field and others is that it is larger than the others.

Has anyone come across this problem before? Could there be some other property that I have overlooked that is causing the problem?

I am pulling my hair out at this one (and at my age I don't have too much to lose)
