link to a file with extension .3gpp does not open that file

[mtb]

When I open a .gpx file created by 'OSM tracker for Android' and then in JOSM click on a waypoint with a link to a sound file (extension .3gpp ), the assigned Windows media player does not open. Thus, I cannot listen to my voice recording directly from JOSM (from Windows explorer, it does work).

I use Windows XP, latest JOSM version 3751, Java 1.6.0_22

I tried old JOSM versions from ​http://josm.openstreetmap.de/download/ and found out the following:

• until and including version 3522 from Sep 11th, it still works fine (i.e. media player opens)
• but as of the next version available on ​http://josm.openstreetmap.de/download/ (that's version 3525 from Sep 14th), nothing happens at a click on the waypoint with a link (i.e. error occurs).

In the .gpx file, the waypoints are stored like in the following example:

<wpt lat="49.41648244857788" lon="8.417962789535522">

<ele>140.0</ele>

<link href="2010-12-30_16-29-25.3gpp">

<text>2010-12-30_16-29-25.3gpp</text>

</link>
<sat>9</sat>

</wpt>

Thus, my request is: would you please enable direct link to the .3gpp sound files as it used to be until JOSM 3522?

Thanks and regards,
