Auto PNG file save problem under Windows XP SP3

Hi,
maybe you are still saving DHS files, just changed the name to end with .png? You should do this:
 
1. Click "Capture Settings" button on the "Capture" ribbon tab.
2. Click the "Quick Save" tab
3. Put check-mark into "Automatically save each capture to a file field.
4. Click the "Change" button next to "File Name:" field
5. In the "Save As" window that appears now, navigate to a folder where you want to save your files, and enter the base file name, e.g. "MySnap".
6. Click into "Save as type:" field below "File name" field, and select "Portable Graphics PNG" file format.
7. Click "Save" button
8. Click OK in "Capture Settings" window.
 
Now the program will save valid PNG files.

My experience with 7.29.02:
I am presented .png as default. If I use Save as "jpeg" (.jpg), the current capture is saved as ,jpg, (I don't see  "Capture Settings" window) and I am still presented .png at the next capture. What I am looking for is a default "save as .jpg"
