I am confused about the relationship between the designer and the associated HTML file.
If I edit the HTML file the changes are not shown in the designer but do appear when I test. Subsequent changes in the designer are not then reflected in the HTML. I see from previous questions that you can 'undo all source changes' from the Web Resources menu and the designer changes will then show up again in the HTML. However I do not want to undo all changes as for example css changes need to be kept.
It makes it difficult if the HTML and designer are not in step or have I got the wrong idea?
