Greetings,

Today I released a new WinQuake (WQ) beta release. Links to the new release
can be found here: http://www.seismicnet.com/software.html. This release
has the following features as will as some bug fixes;

The event, or seismograph, window now displays the time and amplitude of
the cursor as you move it within the window. This information is displayed
on the Status Bar. For the amplitude the number is in A/D counts. For the X
or time axis WQ will display the time down to the millisecond, if you zoom
down to a 10 second or less X Scale.  Too get 1 ms resolution WQ
interpolates the mouse location between samples since a true 1 ms
resolution would require a sample rate of 1K hz.

I fixed several problems around saving event files as SAC binary files. WQ
now save the event time in the proper field. The problem is I'm not sure if
I'm doing it right. If you have access to another program that can read SAC
binary files and if that program can display the event time please contact
me...I also save the event magnitude in the USER1 field. As far as I can
tell there is no defined field for this??? I noticed that the SAC binary
created by the IRIS Spyder
(http://dmc.iris.washington.edu/DOCS/spyder_alt.htm) system was using USER1
for this info. Unfortunately they do not fill in the event time, so I can't
check to see if I'm doing the event time correctly.  

The major new thing with this release is the PSN Explorer program I wrote
in the last few weeks. First some background.. When I started using HTML
help files for WQ, Netscape users had no problem using them. People using
M$ Internet Explorer would run into a little problem with going to the
correct part of the web page. With Netscape, WQ could open a local (on the
users hard disk) web page file and have the browser go to the proper
section within the help page. Internet Explorer would open the correct
page, but would not go to the HTML name tag (sometimes called a bookmark)
within the page. Too get around this problem I used a new feature in VC++
6.0 that lets you create your own program and use Internet Explorer 4.0
(and above) to display web pages within the users program window. 

Buy creating this new program I fixed the help problem and also was able to
easily add a feature to the PSN Explorer that allows the user to download
event files from a web page and have WQ open the new file after the FTP
download. Heres how too use it. In WQ I added a new tool bar icon next to
the report icon and menu items under View. Selecting the New Event File
item, WQ will open the PSN Explorer program, or use one that is already
open, to display the New Event File page at
http://www.seismicnet.com/cgi-dos/event.exe. The user can then select
either the GIF image link, this will be displayed by PSN Explorer, and / or
select the PSN event file link. If the event file is selected the program
will download the file using FTP and then send a message to WQ, using DDE
(a way of communicating between programs In Windows), that tells WQ to open
the new event file. Before using this feature you must select a directory
that will be used for downloads. This only needs to be done once.

If you download the new release and find any problems please let me know as
soon as possible. I want to get WQ out of beta soon. The next thing, the
part I hate the most, is updating the documentation....
