Madsonic Support

Version 4.8.beta2 (build 3292) – December 6, 2012
Server Apache Tomcat/6.0.35, java 1.7.0_05, Windows Server 2008 (158.3 MB / 230.2 MB)

I just tested my server and it's accepting a tag edit just fine.

since Build 3300 a new libary is included, hopefully this fixed it.

best regards
