Tmux borders are drawn with dashed lines; how can I change them to continuous lines

Old post but anyway for people looking into this still. I find it best to set a different font for Non-Ascii characters and my actual font used for ASCII characters.

For reference I use Menlo for Powerline for Non-ASCII and Droid Sans Mono for my ASCII font and this sorts out the vertical line spacing without faffing around with vertical spacing etc.

I figured out the problem. If you use the default Terminal.app, the mouse events are not being passed to the applications running inside the terminal. To fix this problem, you need to install MouseTerm, which requires SIMBL to be installed. You can find all of the instructions here:

Note that if you're using Mac OS X 10.9, when you try to run the install script for MouseTerm it will say that the file is corrupted. To solve this problem, just manually copy the bundle file to the SIMBL plugins folder and restart Terminal.app for it to work. You can find the SIMBL plugins folder at this path:

/Library/Application Support/SIMBL/Plugins
