I now have SnagIt 13.0.2 and I am no longer able to accurately capture web pages. When I use the "Capture Vertical Scrolling Area" feature, it hides parts of the page, and sometime adds more! This is frustrating because I rely on screenshots to communicate instructions effectively to my users. Please fix this bug!
If your mouse wheel has Tilt Left and Tilt Right functionality. You can do accurate left and right Panoramic Captures without the up and down deviations you get with dragging manually.
It's saves you the step of cropping to get a neat capture in post.
I was able to fix the issue by entering fullscreen mode first (in Chrome, go to View > Enter Fullscreen), then capturing the screenshot with Snagit.
Simple, but totally fixed the issue. Try it out.
Entering Full Screen before capturing the scrolling region is the only way I've been able to fix the issue.
