Sorry for delay; been out of town. All functions including saving and recalling routes are working fine now. Thank You. I use Windows 7 and Chrome.
By Marvin on 07/03/2015
There weren't any java script errors appearing in either browser. I've just checked it (at 00:30 GMT, 26/2/2015) and my saved maps are loading for me.
By CassidyGF on 25/02/2015
CassidyGF, can you see any JavaScript errors in your browser? Thanks
By Daft Logic on 24/02/2015
I've tested this on both Chrome and Firefox, and on two different computers on different op systems. I can log in, but I can't bring up anything.
By CassidyGF on 24/02/2015
Hi Marvin, is this still and issue? Which web browser are you using? Thanks
By Daft Logic on 24/02/2015
Hi CassidyGF, which web browser are you using? Thanks
By Daft Logic on 24/02/2015
I'm like the others; nothing is working for me, either. It doesn't seem to want to get out of the log-in state.
By CassidyGF on 21/02/2015
The last couple days the search and all general map functions work, but clicking on a saved route or clicking save new route do nothing. I have cleared my chrome history/cookies & restarted Chrome, but no change. Have used this app with Windows 7 & Chrome for years with no problems. Maybe the last Windows update??
By Marvin on 20/02/2015
Hi, can you try deleting your temporary internet files and then reload the page again?
By Daft Logic on 18/02/2015
I've been trying to use this site for the past 2 days, but the map has not loaded. Any ideas?
On 18/02/2015
Hi, Elevation should now work on the 2nd, 3rd click ...
By Daft Logic on 11/02/2015
Great app. The elevation button does not seem to work unless I reload the page. Thanks!
On 05/02/2015
Tom, we haven't changed anything. It should appear up at the top right of the map. Do you see anything up there?
By Daft Logic on 16/12/2014
I used to have option of satellite or map view. Not able to as of last week. Why? Thanks

Hi Rita, It should now work again.
By Daft Logic on 16/11/2014
Is there a limit to the number of routes I can save? I have tried using different browsers but the 'Save new route' link does not produce the box where I can name the route
By Rita on 16/11/2014

I'm trying to use the Advanced Distance Calculator with Google Chrome but I can't find the user option menu to save my route. Is it supporte Chrome browser ? I'm doing wrong something ? Cheers Marco
On 22/09/2014
Exactly where is the "save new route" command? I can't find that, nor the "user options".
By Joe on 24/08/2014
geographer, Download KML is still there. Can you not see it?
By Daft Logic on 17/08/2014
has the xport route to KML option been removed?
By geographer on 16/08/2014
Never mind my previous comment. Fixed by enabling trackers.
By Martijn on 28/07/2014
The map won't load anymore. It worked fine last week.
By Martijn on 28/07/2014
yes, I enjoyed using this distance travel site since later this year(2014), I am planning to travel from U.S. to Ukraine to meet person to person my sweet heart 20 year old gal. I want to download your site. please send me a download app via by my email address. you should already have my email address. thanks
By james j. vanecek on 21/07/2014
Hi Robin, there is no way as such. Just stop clicking.
By Daft Logic on 01/07/2014
How do I end the route definition process? Because after I have named and saved a route the cross is still there and active and clicking it just creates another marker.
