Hello,

I am working with images with overlays that cover the entire image. I need
to draw circular ROIs with a given center point on the images for numerical
analysis. However, the Ctrl+Shift modifier keys needed to do this with the
Oval Selection tool make the overlay come off and move around instead of
drawing the circular ROI that I need, i.e. the overlay gets selected.

Is there a way to solve this by 1) reassigning the modifier keys, or 2)
make the Oval Selection tool give a circle with a given center point
without using Ctrl+Shift, or 3) make the overlay stick in place? I can't
see any options in the ImageROI or Overlay code that allow for an
"immobile" overlay (the images are produced by a plugin written by me.) And
flattening the image is not an option, since I need the pixel values
underneath.

Greetings,
David
