In OOo Writer 3.1.1 on Kubuntu 9.10 the highlight-middleclick paste feature
works only so long as the original text is highlighted. Other apps, such as Kate
and Firefox, make the paste available even if the highlighted text is no longer
highlighted.

Steps to reproduce:
1) Open new Writer window, type "Hello, world!", and press enter 10 times
2) Highlight the word "Hello"
3) Move the mouse pointer down a line or two and press the middle mouse button
4) See the text "Hello" pasted where the mouse cursor is
5) Now click somewhere on the screen to remove the highlight from the original
"Hello"
6) Move the mouse slightly below the second "Hello" and middle click
7) See that there is nothing pasted
