Hello, I just downloaded and installed Freesurfer and I had just a few basic questions.  1. When I type in the command to "test the installation type" using "tksurfer bert lh inflated -annotation aparc" I get the bert brain image, however I don't get the tksurfer tools popup below it with all the different icons and options and I don't know why?2. When I go to the GIMP image editor just to explore and play around with it, I selected the paint brush to draw on my selected image, however when I go to change the color from black to any other color (and it shows that I've selected a different color) it still draws/paints black on my image? Thank you for time and help!-John M.
