I'm getting quite a few glitches with Nitro in Nuendo 2. Here is an example log file produced by Nuendo. Hopefully it will be of some use.

Any comment available please?

Could you please describe the circumstances of the crash? Was the audio playing/stopped. Did you change the preset when the crash occured? Did you launch or close the plug-in or its editor window? etc... Unfortunately I am unable to tell you anything by just looking at the report you sent.

Well, here is one way to reproduce it.

Open a new project, add a track and stick three Nitros as inserts on this track.

Don't hit play or anything - just repeatedly open and close the Nitro windows and after about 10 clicks, the whole lot will either freeze completely/generate a neundo2.log or generate a windows error.

So, no audio playing, no preset changes, just opening and closing the Nitro windows causes this.

Thanks. This description will allow me to investigate the bug and (I hope) get rid of it.
