CW speed out of control

Knut Meland

Using Winwarbler for keyboard CW keying I experience that my 20WPM speed suddenly changes to more than 100WPM. 
Ii usually happens when i have some words in the type adhead buffer. 
It happens when I work with 100W output as well as with 5W. 
Is this a common problem?
How can I fix it?
All ideas welcome..
