1. Is this a network program?
Currently, we do not recommend that this program be run from a network. Due to the small size of the program files, we decided that this feature was not needed. The entire program including support files is only about 6 1/2 megabytes.

2. I am having difficulties installing the program. What do I do?
Make sure to close all programs that are open as this may prevent proper installation. Be sure to close any programs that may be open or minimized on the taskbar. Reinstall program. Reboot computer.

3. I am unable to view the 'Loss Coefficients (pdf)' from the Help menu. What is going on?
This file requires the Adobe Acrobat Reader program available at http://www.adobe.com/products/acrobat/readstep2.html. This program is free and is used to view/print pdf files.

4. In the preferences screen, what is the difference in 'Lost focus', 'Change' and 'Use Calculate' buttons?
This preference was added to allow the user to choose when calculated results were displayed. The 'Lost Focus' selection will recalculate when you move to another field. The 'Change' selection will recalculate after every key press. The 'Use Calculate' button will display a calculate button to click to perform a recalculation.

5. I would like to look at the loss coefficient data used in this program. How do I do this?
All coefficient data is contained in a text file with a .tbl extension. To view this data, choose a fitting, and from the File menu, choose Preview Tbl...
