Can't delete users in asterisk-GUI

Hello all. This is my first post here, and my experience in Asterisk is getting close to the 12 hour mark, so excuse me for being a little slow.

I’ve just installed Asterisk and asterisk-GUI (Prior to my discovery of AsteriskNOW. Darn!) and it works great. A lot easier and reliable than Trixbox, in my opinion. However, whenever I try to delete some test extensions I created in the Users panel, all of the extensions in the menu become highlighted and the delete button is greyed out. Is there something I’m missing? A keyboard shortcut? A click? Any help would be much appreciated. Thanks.

Never mind. Solved my problem. It works fine on my office computer for some reason. Sorry!
