Hello,
I am very new to this software and it seems like I’m having a similar issue.
However, the painting doesn’t work either. Whenever I draw/paint then let go, the drawn area just disappears.
Should probably let you know that the files I’m working with have an error " Multi-frame image. If slice orientation or spacing is non-uniform then the image may be displayed incorrectly. Use with caution.
Reference image in series does not contain geometry information. Please use caution."
I don’t know if this is what’s making the annotations disappear. If you have any ideas on why this may be that would be great.
Below is a screenshot of the issue (I can draw/paint, but once I release the mouse or right click, the area doesn’t get shaded but just disappears)
Thanks a lot.
