--- Comment #11 from Vidar Haarr vhaarr+wine@gmail.com 2009-05-29 10:25:58 --- I went to the Ventrilo website and to my amazement they've released several new versions since the one I'm using (3.0.1), so I couldn't find a download link for that version there. http://dailyfreeware.net/2007/11/21/ventrilo-301/
I've never used the site linked above, it was the result of a "ventrilo 3.0.1 download" search on google.com.
I'm going to upgrade to 3.0.5 (available from ventrilo.com) locally, because there's several other good fixes in these versions. "Hopefully" the bug will be present in this version as well in case you need me to test any further.
