I don't know if it's an issue with the computer or with Scubalog, but every time I download my dives, it tells me I have 0 pressure in my tank. When I go to the graph, I can pull the end dive pressure off of it and manually input it. While not a show stopper, it's a bit of a pain in the ass. Scubalog is up-to-date and it tells me the firmware is as well.
