    Hi Fred,

    >Once you try it, it will be obvious.

    I had already PAN>ZOOM>PREFETCHED, at least locally, fairly heavily. How much the DRIVE OVERLAY was doing was not obvious since the fetched tile count was low. I "drove" a GPX for a road trip of 150Mi and only fetched about 70 tiles. I had already been through there along the intended route prefetching.

    I am running RF on the road, so I have the purger turned off, and I have archived my tile files at home, so i might not need to download much for quite a while now. I have a library of three sets that cover just about everywhere I might go. I expect my overall tile download is fairly low, spread out over the past year or so, even though I am supporting 3 computers here.

    > I travel with a tablet.

    I think you said you were running a DT360. The bottom plate on mine runs at a measured 115F+-. That seems hot, even if it's a heat sink. How does that track with yours?

     >When I "drive", rather than use my tablet, I'll take my USB drive and plug it into my desktop and start the instance from the drive.

    I don't want a flash drive sticking out of the tablet while on the road. I build the GPX on my Win7 machine, then transfer it to the tablet and let the tablet fetch while I do something else. the tablet is getting a bit crowded on memory, I don't even keep the GPX on the tablet. 4Gig isn't as big as I thought it would be <G>

    Thanks and 73, KC8SFQ  Ron
