Text/Font problem?

Using Coreldraw X3 the problem I have is new I have never encountered it before. I type a word and as long as the cursor remains in the text of the word all is okay as soon as I click outside the text it goes black as if it is in bold mode but it is not if I put the cursor back in the word it returns to normal. I am using arial 10pt. and have tried other fonts and they do the same. If  I start a new drawing and type the words that I want and copy/paste into the drawing I am woking on it is fine no problems. Any answers would be appreciated.
