You could also highlight the place you want to 'fast travel' to, then click the 'fast travel' button at the lower left of the screen.
Sometimes double clicking doesn't cut it for me either. Especially if I have been at the Brewer's finest.![]()
You are supposed to double click to select it, not wait for the hover over. Also if you are in a zone you haven't done alot of the quests for then zoom in so you have a better chance of clicking on the correct location.
Pro tip: use the arrow keys to highlight to the fast travel and then hit "enter".
Sadly I quickly realised although this game is a godsent for PC, it was built for consoles and effort to make it PC playable was.. Minimised.
I learned to highlight and hit enter because double clicking I often had trouble with cursor moving between clicks and the spot to highlight is so small it wouldnt work. When they added the Fast travel at Iron Demon ranch some complained because it was out at road but I thought it was better because you can at least highlight it without the other stuff right next to it.
Mouse over it and hit enter is the most trouble free way for me when there are mission points are other crap in that same area.
