!!! NeroFiddlesCOM.NET does not exit the process !!!
Nor does any other .Net application that created an instance of Nero using Nero COM for .Net from SDK 1.08.
This started to happen for Nero version 184.108.40.206 and up (Including Nero 7). I believe it worked just fine up to the version 220.127.116.11
If you are using VS 2005, you have to disable VS hosting process to replicate the problem.
I have run a lot of tests on diferent machines with different Nero versions installed and I am confident that this is a bug in a Nero software that was introduced in version 18.104.22.168 and up (or may be a little earlier).
I would hope that Ahead will take a look into it ASAP as all our applications will not end up with Nero updates installed. ! ! !
