I have the following script and csproj available in a NestingBug.zip file, how would I attach or upload the zip file?

trackMaskLeft.CompositeMode = CompositeMode.Multiply;

// This is where the script hangs !!!
trackVideoLeft.CompositeNestingLevel = 1;

trackMaskLeft.ParentCompositeMode = CompositeMode.Add;

trackMaskRight.CompositeMode = CompositeMode.Multiply;

// This is where the script hangs !!!
trackVideoRight.CompositeNestingLevel = 1;

trackMaskRight.ParentCompositeMode = CompositeMode.Add;
}

Do you have webspace where you could upload the file and then post a LINK to the file? Then we could download and test it as well.

Dear jetdv,

The NestingBug.ziq file contains the source and project files.

As of this point, I can say two things:

1. Your DLL files locks up Vegas Pro 8.1. I have to kill it.

2. If I take your CS file and remove the "Partial" from the class, I can run the CS file directly in Vegas Pro 8.1 and it works.

The "partial" keyword was from the original script that has a UI.
I removed the "partial" keyword and recompiled the NestingBug.dll

I tested the revised NestingBug.dll and NestingBug.cs on two machines.
Both the dll and the script file worked properly on the XP machine.
Both the dll and the script file HUNG Vegas on the Vista machine.

Since the NestingBug.cs script failed on the Vista machine,
we can address dll issues later.

Commenting out the following lines allowed the script to run on the Vista machine.
// trackVideoLeft.CompositeNestingLevel = 1;
// trackVideoRight.CompositeNestingLevel = 1;

Since the CompositeNestingLevel was not set there were appropriate warnings
when executing the following lines.
trackMaskLeft.ParentCompositeMode = CompositeMode.Add;
trackMaskRight.ParentCompositeMode = CompositeMode.Add;

Did you run the original NestingBug.dll with Vegas 8.0?
Did you run your revised NestingBug.cs with Vegas 8.1 on a QuadCore machine?

I do not have a Vista (32bit) machine running Vegas 8.0.
Can you test the revised NestingBug.cs on any other machines with Vegas 8.1?
