I am using Lectora 11.1 and the browser we unfortunately need to target is IE8. When you close the lightbox, the window closes but the transparent gray background stays on the screen and locks the window from user interaction. The only way to continue is to refresh the page.
There is a downloadable solution (library object) from a similar thread here. Has anyone else encountered this and come up with a better solution? Is this a known issue and slated for a future patch?
