Awhile back, an e-mail account was set up by support at Trivantis specifically for Accessibility concerns. I’m trying to locate that information to post here. Meanwhile, if you haven’t already done so, I suggest submitting a ticket to Support@Trivantis.com or use the online support ticket to report the issue.
You’re also welcome to join the Lectora Accessibility User Group (LAUG) via the link provided. We meet (phone discussions) the last Thursday of each month form Jan-Oct. It’s a great forum for asking questions. http://thelaug.org/index.html
