I would like to add that I have been having problems with 3.80. The issue is that it occasionally hangs on start up at the loading waypoints and tracks screen. I thought it might have been caused by my computer going into sleep mode when the gps was hooked up or I thought that maybe I wasn't "safely" ejecting the device, but after a few times of making sure I did, it wasn't consistent either way. I should also mention that I have no custom symbols in the directory. I am going to revert back to 3.60.
