I get the prompt: "Please select the original FROG2.INI".
The application wants to know where it can find media on the CD-ROM. Make sure the CD is on the drive, Select your CD-ROM.

I got the message: "Could not find <c:\FROG2\media\INTRO\I101BKG.PIC>"
The application could not find the media on the CD-ROM. Run The Digital Frog 2 again and when prompted, select the FROG2.INI file on the CD.

I got the error: "This program requires 16-bit QuickTime for Windows."
You need to install QuickTime 2.1.2 from the CD. It can be installed in addition to later versions of QuickTime. If it is not installed on your PC, open the Qtinstal directory on the CD then run the Setup.exe file. Follow the on-screen instructions to complete the installation.

I got the message: "This display device does not support 640x480 pixels and 65536 or 256 colors!"
The Digital Frog 2 requires that the color depth of the monitor be set to at least 8-bit (256 or thousands of colors) and at a resolution of at least 640x480. To change this, use the Windows Setup program to choose a video driver that supports this bit depth and resolution. If you have already tried this and are still getting an error, you will have to install the Microsoft SVGA 640x480 256 color driver included with Windows (also available on the CD-ROM, in the SVGA directory).

Some pictures show up surrounded by a colored box.
The Digital Frog 2 requires some images to be transparent. You will need to edit the FROG2.INI file, in the C:\FROG2 directory. To change this:
     1. Open the file FROG2.INI in a text editor
     2. Change ;transparency=driver or bitmap to transparency=bitmap
(Make sure that you remove the semicolon at the beginning of the line.)

The program crashes and/or I'm getting a General Protection Fault message.
These problems are often caused by conflicts between software programs installed on your machine. There are several things you can try:

    Make sure you have the latest version of 16-bit QuickTime installed. The version number can be obtained from the QuickTime control Panel. The version included on The Digital Frog 2 CD-ROM is If the version that you have is earlier than this, make sure you update it.

    Turn off video acceleration in your display control panel. This is usually found under "Control Panels: Display: Settings: Advanced Properties: Performance". Drag the Acceleration slider from Full to None.

    Ensure that you have the latest version of your video drivers. Check the web site of the manufacturer of your video card to download the latest driver. (Note: There have been some problems specifically with ATI Rage video drivers and QuickTime that have been fixed with the latest version of the ATI Rage drivers.)

The program runs fine, but the text isn't formatting properly.
The fonts Helvetica or Times may be corrupted or not installed on your computer. Both are required for the proper running of The Digital Frog 2. To fix the problem, simply re-install the fonts from your original system disk.
