I am please to announce that as a result of the continuing efforts of Chris, Alex and the great folk at STACK DragMath v 0.7.8.2 has been released featuring some improvements in DragMath and the release of DragMath as fully GPL3 complaint. See the plugin db page or moodle docs page for details vis-a-vis obtaing the special DragMath integration file that includes all integration files and the DragMath code.

We have reports of possible issues with v 0.7.8.2 on OSX, but would like some assistance from users in determining where any problem may lie. As the applet seems to work fine when pointed at it's home demo page, I am thinking any issues are likely local (cache conflicts etc) but we obviously want to confirm that.
I have been able to test so far with Safari and that works fine, but FireFox seems open to doubt at the moment. We would appreciate it if those installing the update who have a Mac to test with sanitize & upload or email to me console data and observations on behavior so we can determine if this is a local artifact, some issue in FF, etc.

I can confirm dragmath v0.7.8.2 doesn't display in moodle 1.9.8 html editor for firefox 3.6.3 on macosx 10.6.3. This was a clean install not an upgrade from an older dragmath version.
Thank you for the report. Please provide details of what you observed as well as the java log.
+ server/apache error / access logs ...
The only error I see on Windows environment is
"GET /m198/lib/DragMath/applet/META-INF/services/javax.xml.parsers.SAXParserFactory HTTP/1.1" 404 1184 "-" "Mozilla/4.0 (Windows Vista 6.0) Java/1.6.0_20"
that we discussed some months ago but it does not seem to have any impact on rendering dragmath on Windows (all my test browsers render the latest DragMath on Vista)
I've installed dragmath in my site with moodle 1.9. In ie it works, but in firefox on linux (ubuntu 10.4) it doesn't work. I get a white window without any button.
Maybe your Ubuntu Firefox is missing some java plugin - see for example http://ubuntu-virginia.ubuntuforums.org/showthread.php?p=9016679 (similar applet not initialized message...)
So you might need to do something like
sudo aptitude install sun-java6-jre sun-java6-plugin
Tanks, Mauno!
I've already installed java plugins on my Ubuntu, because I use other java application (as geogebra, for example).
I'll ensure that nothing of java plugin is missing.

Chad,
Starting in Firefox 3.6, you also need the new Java plugin included in Java 6 Update 15 and above.

Does it help if you try the Software Update feature to upgrade your java?

Thanks, Mauno. Your suggestion sorted issue. I upgraded to Java for Mac OSX 10.6 Update 2. Dragmath now displaying ok for firefox on mac.
Hi
I would like to know is it possible to open LaTex expression in dragmath by using openWithExpression parameter.
I can test it at http://www.dragmath.bham.ac.uk/demo_Maxima.html, it is allow to use Maxima format.
Even with Maxima format at http://www.dragmath.bham.ac.uk/demo_Maxima.html, some expression can't display correctly.
e.g. 4th root of x ==> (x)^(1/(4)) is display incorrectly like x (1/4)
When I tried with LaTex, I get "Expression could not be parsed" Error only.
My goal is to allow user to edit thir existing formula with dragmath.
After user create a long formula and when they want to change some value, it is difficult to look and change value in LaTex string.
So if I can open this formula in dragmath, user can easily find and change value in dragmath.
Any suggestion on it?
Thanks

Unfortunately openWithExpression supports only a subset of Maxima expressions - see this post by Chris:
Thanks for your reply.
Is there any workaround to load existing formula into dragmath?
To achive this, if we need to change current format LaTex to other format, it is ok, we can change format.
I note that there is save and load express from file feature in dragmath,
Is it possible to call "Save Expression to file" function to save the expression to hidden html field instead of .drgm file?
Then saved expression will load in dragmath from this hidden field to allow the user to edit the expression later.
