Directions to locations outside of the starting
address's US state cause the program to hang and use
100% CPU power. I noticed there was a todo for cross
country travel but wasn't sure if it was referring to
this problem. I'm using Windows XP x64 with the
Roadnav v0.12 binaries.

    It's a related issue. There's no fix at this time, but it's
    one of the highest priorities issues facing Roadnav at this
    time. In the meantime, make sure you've downloaded maps for
    all of the counties that the route will pass through.
    Otherwise, Roadnav will definitely hang trying to find a
    path from the starting to ending point.

    I saw the same thing trying to navigate from Mountain
    View, CA to Anaheim CA.

    I discovered RoadNav as I was feverishly packing to go to
    Disneyland, so this was my first attempt to use it. It
    seemed to be continuously trying to recompute the route
    and never succeeded in displaying anything.

    I'll try to play with it some more this weekend and see
    how it behaves on shorter routes.

    I was running on a hyperthreaded 3.0GHz 32-bit laptop, so
    I don't think the problem was that my machine was
    underpowered.

    I just saw your reply. That could well have been the
    cause of my hang too. The program seemed to automatically
    download the maps it wanted for the start and end of the
    route, but not the counties in between.

    Hmmm... I'm surprised that the major interstates aren't
    just part of the base map. If they were, I think that
    would make the problem easier (rather than harder) as the
    program would just have gotten me onto I-5 and then it
    wouldn't need local road information until it got to
    Orange county.

    Mark,

    What version of Roadnav are you running?

    I'm running RoadNav 0.13 (just downloaded last Saturday
    evening).

    Now that I'm back from Disneyland and have internet access
    again, I'll try playing with it some more.

    I have some ideas for enhancements I'd like to experiment
    with if I get a chance.

    I gave it another try just now, with a MUCH shorter route
    (my old commute, between zip codes 94043 and 94040).

    It first computed a route and then went into a loop
    continuously recomputing the route, but never letting the
    UI do anything.

    I turned off the voice prompts, but that did not seem to
    help matters. I may have to try building it myself and
    seeing what I can find in the debugger.

    It looks like in my case, the problem may just be not
    enough real memory. I took a look at task manager and
    found that Roadnav's VM size was about 750MB, and I only
    have 512MB of real memory on my laptop.

    How much memory is requried to navigate and is there any
    way to tune it down or do I just need to add more memory
    to use the program?

    Routing eats up a lot of memory, but 512MB should be enough.
    Is that 750MB when it's computing the route, or 750MB after
    it's done?

    Also, what address are you trying to go from and to?
