Did you update to 4.1?
Yep 4.1 is installed

Here on a PC it works fine. If you grab the handles in the program monitor nothing happens? No black areas apprearing outside of the handles? Have you had this before? Did you update your video driver in the meantime? Just shooting from the hip, since I am not familiar with MAC.
Yes your description is correct when the handles are moved the background does not turn black. I am new to this software package and I am going through the Adobe Classroom in a book for PPCS4, so I am not sure I have missed something but I have done this particular lesson to the letter. This is the first time I have had this problem and as far as I am aware the video card drivers are up to date. So I am assuming it may be a bug of some description if I can't get an answer here.
Thanks for your help so far. Any other suggestions?

The reason that Harm asked about the CS4.1 update is that WAS a Garbage Matte Bug in one, or more, of the earlier CS4 updates. CS4.1 fixed that - or at least for the PC.
A frequent contributor (and MOD) here, Curt Wrigley, actually wrote the CiaB PrPro CS3 and CS4. I do not know if he personally tested everything on both a Mac and a PC, but know that all lessons WERE tested on both platforms. Maybe he'll stop by and comment specifically on the Mac.
Thanks for your reply.
I have 4.1 installed and as far as I am aware I am up to date with all software.
It is a ball ache but I have a work around so all is not lost. I must now assume it is a bug and hopefully Curt Wrigley may drop by and put me out of my agony. I am at present doing a BA in photography so don't have a large amount of time to spend on resolving software conflicts/problems etc. Luckily I can usually find a work around so can get on with what needs to be done for my degree.
Once again thanks for your input in helping me. It is much appriciated.
All the best
Well, I am working with Premiere Pro CS4, version 4.2, and having the same problem with non-functional garbage mattes. I'm running on an Intel dual-core laptop with OSX 10.5.8.
Herewith the report:
Four Point Garbage Matte does not function.
1. Place a video in layer Video 1.
2. Create a new matte (I created a red matte named "Red Matte").
3. Place the matte in layer Video 2.
4. Adjust the length of layer Video 2 to match Video 1.
5. Drag Four-Point Garbage Matte effect onto layer Video 2.
6. In the Effect Controls for Red Matte, select the garbage matte and drag the handles towards the center of the image in the Program panel.
Results: No results. Nada.
Expected results: Only the interior area of the matte, a red quadrilateral, should appear superimposed on the video in layer Video 1. Areas outside the matte should be transparent.
Same problem with other garbage mattes.
I thought this bug was fixed in version 4.1! What a nuisance.
Yes still got the same problem and wonder if it will ever get fixed. On days like today I could kick the software into touch. Frustrating.
It works as expected in Windows, so I must assume it continues to be a Mac-only bug.
Transparency issues in Pr can often be solved by nesting sequences. Right-click (context menu) the red matte track item and select Nest. Do you get the results you expect? Open the new nested sequence and move the matte to track V1. What happens then?
Thanks for the suggestion. I tried nesting and moving the red matte to Video 1 in the nested sequence, but no joy.
I ended up using a linked composite in After Effects, where the matte behaved as desired, but its not a solution I like. There are some side effects. Video preview seems choppy and transitions that I put in before AE compositing have to be redone.
As with Paul no change but thanks for the suggestion.
