unable to highlight portion to be deleted

using audacity ver. 2.0.3 windows 7 64bit sp1

Im trying to delete the 1st 19 seconds of an audio file ( mp3 ) . it wont allow me to highlight and cut . I have checked the help section and the online tutorials… lets me pick the area to be cut… but all buttons are greyed.

As per http://manual.audacityteam.org/o/man/faq_editing.html#snap , you may need to uncheck Snap To in Selection Toolbar to make very small selections of less than a second.

For any selection, you have to press the yellow Stop button before you can edit:
