Unbolding text problem

Hi guys,

When I sometimes paste from Word, a line of text may be in Header 1 format.

I can change the font size, of course, but when highlighting the text I cannot turn off bold on the phrase by clicking 'B' on the toolbar. I need to:

- highlight only part of the phrase
- click 'I' to italicise (may work with other buttons, I don't know)
- THEN click 'B' to debold
- then click 'I' again to turn off the italics.

Does anyone else have this problem? Is this a fix, per chance?

Thanks!
Mark
