We are using de GPStools-plugin to display GPX-tracks in the module Events Booking. When using this plugin, the download-button does not start a download but will put the cursor to the top of the window.
When I open the samen GPX-track in the GPStools-frontend, then the download-button is working fine.
I think this problem has been introduced in version 5.1.8., when the possibility to alter the download-name is introduced.
