No longer able to move opbjects that I have drawn on my capture.
Depending on the version of Snagit being used, this can be caused by one of the following....
The image has been flattened
Once an image has been saved from Snagit as a shareable format like PNG or JPEG, the image will be flattened. This means that all of the objects that have been drawn on the image will become part of the image and will no longer be editable. This will occur after the image has been saved, and then the image has been closed from the Editor.
If you would like to be able to come back and make changes to your edits, save the source image as a .SNAG file to a safe place on your computer. When you need to make changes, open the .SNAG file, and you will be able to edit the objects. Then save a new copy as a PNG or JPEG to share (so that you always have a copy of your "master" .SNAG file.
Object was not created as a vector
There is an option under each of the draw tools, under effects called Create as Vector.
Make certain that this option is checked, or else anything created with that drawing tool will be automatically flattened. This setting is specific to each tool
