Lector 12 Images and Question Feedback

[ATTACH=CONFIG]630[/ATTACH]

I've been working with Lectora 12 for about a month now and I've noticed a few things. One is if I import an image and crop it in Lectora, and then add a border. When I preview in browser the border appears thinner than images that have not been cropped. I'm afraid that if I publish it, that's how it will appear.

See attached image.

Also, I was wondering if anyone else was having issues customizing feedback for questions. I originally selected the "Enable Feedback option" for a course that I published out for internal review. The reviewers decided they would prefer a customized images as feedback. Therefore, unchecked the "Enable Feedback" option and imported two images that were initially hidden and read Correct and Incorrect. I had no issues using actions like: OnSelectChangeShow_img_Correct, OnShow(Correct)Hide(Incorrect), for Multiple Response and True/False questions. However for all my Multiple Choice questions I've had to delete the entire page, and recreate it from scratch for the actions to process and show feedback.

Anyone else noticing either of these?
