Rated 4 out of 5 stars

I have upgraded to Ubuntu 14.04 AMD 64 and I find that I can not choose all the text in the defaulting directory location. In the past I would type Ctrl A and the whole line would be highlighted. I could then delete the line and search for the correct destination. Ctrl A no longer works for me, and I have to use the delete key to slowly delete the whole line. Any ideas as to what to change?
