Disappearing bullet points and invisible list

I did not see these listed on the known bugs list -

Using version 1.5 on a Windows 7 machine.

When I try to insert bullet points, two things happen:

The bullet points appear at first, but when I close and open the document, they bullet points are gone, although the text is still indented and acts like a list. Specifying “none” in the list formatting menu does not undo the indent.

Most of the time, any subsequent text that I put in after the list, is also indented as though it was part of that list, although there are no bullet points. Specifying “none” in the list formatting menu does not undo this indent.

But when I export the text as RTF and open it in word, the following happens.

If I select the indented text and click on the “un-indent” button, nothing happens.

If I click on the “list” button, it un-indents.

In other words, it acts as though it is already a list, and will only un-indent if I toggle the list button.
