Unfortunately I am not replying with a solution, but am experiencing the same problem. When I open a webpage in Contribute CS5 for editing, blank lines on the page become 2 blank lines on the page, than 3 the next time....you get the point. I've seen a couple forums regarding this but none have a good straightforward answer or a solution, I'm sure people have submitted tix regarding this, but could we get a forum answer please?
This issue might be because of the Paragraph Spacing setting in the Role Setting.
1) Administer the site in Contribute.
2) Select the Role and click Edit Role Settings...
3) In the Edit Role Settings dialog (mentioned below), choose "Two lines, as in web page editors (uses standard <P> tags)" option under Paragraph spacing in the Editing category.
4) Save settings and try the same edit and publish scenario again.
Hope this helps you.
That was very helpful in fact, i've also been trying to insert an HTML snippet too, it says that may cause interference with other settings, what kind of problems might there be if i check allow ? Thank you for reply.
Consider the example, where the Administrator had set some image restriction on inserting image of size more that 80 KB. Then by enabling this option you can insert images of more size through HTML Snippet. So indirectly image restriction setting is overridden. Thats why the message "Enabling this option may override other Administrator settings"is passed.
