Here is yet another situation where '&' is stripped by OCPN causing an aborted download of an important .gpx track file from SpotWalla when using the convenience of a POI.
This simple URL when placed in the browser entry area presents a download box for the .gpx
Try entering the same URL in the content of a POI and it all crashes. Viewing the executing URL at the top of the page reveals that the '&' has been removed.
Substituting the '&' for '&' finally works.
How many other programs will have problems with this '&' exclusion I wonder?
