6.8. About HydraHarp… Dialog
This dialog provides version information on the HydraHarp software and hardware, the latter only if it is
installed an operational. It can be opened via the Help menu or via the toolbar. The button Request Support
opens a small text viewer window that provides a listing of HydraHarp hardware and software versions that you
can copy and paste into your support enquiry. Note that this information is very important for adequate support.
Support requests without this information cannot be processed and will be delayed by return questions for this
information. If your system is not functional at all, the minimum information you must provide for support is the
serial number of your HydraHarp. It can be found at the back of the housing. The dialog also provides buttons
for links to relevant web pages and a button for download of software updates. Note that downloading a
software update does not automatically install it. Typically the downloads contain zip files that must be
unpacked and installed manually. Also note that it may not always be advisable to blindly install the latest
software. This is the case especially when a user or his/her laboratry have developed custom software that
relies on a certain file format. Updates may break such compatibility. Therefore, always study the release notes
before installing.
6.9. Title and Comment Editor
You can use this dialog to edit the file title / comment. It can be opened via double–click on the title, via the File
menu or via the Print Preview Toolbar. The text you enter here will be stored in the data file. The first line will
be displayed as the file title over the histogram display area. The text you can enter here is limited to 4 lines
and 255 characters. Upon loading of a data file, the title and comment will also be retrieved. It will also be
included in prints, if the corresponding check mark is set in the page setup dialog box available through the
File menu.
