[T]his morning I woke up to my html previewer not working at all! Just a blank screen. Sounds like an earlier reported issue. In addition to my suggestions in that thread, make sure the plugin version is 1.4.4, then open the About dialog to see what browser version is detected: [image: 1778880667133-preview_html_v144_noedge_menu.png] Are there any logs or debugging for plugins? Logging is only active when the plugin is built in debug mode. I don’t distribute debug DLLs because the additional instrumentation code usually gets flagged by virus scanners.
