Permian grainstone Having trouble with some part of this tutorial? You'll have to make sure that you meet all of the software and setup requirements in order for it to function properly. Here is a list of frequently asked questions to help solve your problem.

Where do I begin?
Check out the "How To Use This DVD" section.. It will give you an idea of where to start and explain to you how to access thin-sections. The "Suggestions for Instructors" section has advice on how to integrate the tutorial into the curriculum.

What are the software requirements?
Software requirements are listed on the How To Use This DVD page.

Why am I getting a message about connecting to the Internet?
The tutorial user interface is constructed like a webpage using html. It is installed on the DVD using a program, DWebPro, that enables the DVD to function as if it were a server. Some firewalls or other security software may perceive the program's calls to the DVD as an attempt to connect to the Internet. The tutorial does not download any of its content from the Internet, but you may need to adjust your security settings for Internet access in order for the tutorial to run.

Why do I get repeated messages about pop-ups?
The subtutorials utilize many images that can be viewed in enlarged versions via pop-ups. In Explorer a pop-up blocker setting of "medium" will not generate alerts when viewing images in the tutorial.

Why can't I open any of the thin-sections?
You probably do not have Adobe Acrobat Reader installed. All of the thin-sections are provided in layered Adobe PDF format. You will need to have Adobe Acrobat Reader 6.0 (or later) in order to properly view these files. The latest version should be available for download at the Adobe website.

Why does the tutorial look broken in my web browser?
Different versions of different web browsers interpret HTML differently. Older versions may not be able to display certain elements properly, and newer versions might even have slightly different interpretations than the older ones. The tutorial has been tested on Internet Explorer 4 through 7, and should work properly on subsequent versions.

Why can't I open up the larger images?
Many browsers and third-party plug-ins inhibit pop-ups. You may need to edit your browser preferences to allow pop-ups or turn-off your third-party pop-up blockers in order to click on thumbnails and view the larger versions of the images. You also need to make sure that javascript is enabled.

Why are the pop-up images in the subtutorials humongous (or itty bitty) on my screen?
Many of the images used to illustrate features within the sub-tutorials have fairly high resolutions and may appear very large on smaller monitors. Grab the corner of the image window to resize it to fit your screen. Image windows are also scrollable.

Why don't I see the layers in my PDF?
You may not have a new enough version of Adobe Acrobat Reader. You need to have version 6.0 or later in order to have layer support. The newest version should be available at the Adobe website. If you do have the latest version, you probably just need to click on the layers tab at the left of the window.

Why does Acrobat freeze up when I open the files?
The PDF files are very large in order to accommodate the high resolution images that you can zoom up to 1600%. If you are using an older computer, you may not have enough memory to handle it. One thing you can try is only turning on one of the raster image layers at a time. To do that, turn one of the layers off before turning on the next.

How can I copy the photomicrographs and other graphics for use in my lecture materials?
When viewing images in the subtutorials (using the html interface) right-click on an image and select "save picture as". Pdf virtual thin sections can be saved by going to the File menu and using the "save as" option. To copy materials in batches, view the DVD contents and navigate to the "www" folder. Within this folder, various content can be found within the "images", "content", and "pdf" folders.
