Lately (a few days or a week) schematics and little ones in thumbnails are not showing. I use Internet Explorer 11.
In this thread the first post is supposed to have a schematic but I do not see it and there is no link to a schematic: https://www.electro-tech-online.com/threads/question-gain-in-this-circuit.139407/#post-1160548
Later I complained then Eric posted the schematic which I see and can open normally but its thumbnail is blank.
Other threads show schematics (but show blank thumbnails) and I do not know what is different about this one and different about thumbnails.
