Thank you so much for an amazing piece of free software.

When trying to save the display as an image in wxGUI, I get the error
below. No image file gets created. I have tried to vary the contents of
the display, the dimensions of the image etc. but the result is
consistently the same.

Comment:

If I remember, this was fixed at some point. Can you please try to update
to GRASS 6.4.3 and test there? (6.4.3 is the current stable release, if
you want to test this bug also for development/svn versions such as GRASS
7 you are welcome, but the update to 6.4.3 may solve your problem.)

Hi,

as a work-around, you might try the built-in Windows 7 screenshot tool,

Sorry for missing the new stable release! I can confirm that updating to
6.4.3 fixed this issue for me. And thank you for the lightning speed
