Very sorry you are having difficulties. The old layout and software was very familiar after using and building on it for 15 years, but it was table based since it originated before css could achieve the same and more, and so was not possible to support a variety of modern devices; the new platform should be a better foundation going forward.
There were a few aspects of the previous software which were more developed after so many years of use and tweaking, but there are many things which the new software should make easier (e.g. I see the issue you raise regarding attachments posted inline when editing as the editor only shows the attachment number until the edit is actually posted (you can add additional images when editing by clicking
more options) but at the same time, the new system makes attachments in general work much easier with being able to upload multiple at once, being able to select to insert inline at full size which was not easy before and should be useful when discussing a schematic, the lightbox makes it easier to view a number of attached photos, the new bbcode image system allows the site to load over https which wasn't possible before, bb code images don't stretch a post off the page with the new system which was a common issue before, etc. etc.)
Have noted the issues reported (and brought them to the attention of the software developers where applicable for future improvements.)
One question: when you say "so half the width is shown" can you provide a screen shot of what you mean exactly (or email to

Thanks.
