I see. Well thanks for trying. If you can work out how to get your server to handle slash arguments you can fix all your embedded JGloss activities at once. That is definitely the most recommended solution.
As a sample of where to put the code, I have added it to the following file on your Moodle site:
- Course: Latin 1Z03-1ZZ3 - Beginners Intensive Latin I & II
- HotPot: 12.7b Reading Exercise: On the forgetfulness of old age
- File: rosa_gloss.htm
In a standard Moodle 2.x site such as the one you have, there is no way to "search-and_replace" for text strings in the files that are stored in the Moodle database. I'm afraid you will have to alter each one by hand.
Perhaps this site was recently updated from a Moodle 1.9 site? Do you have a backup of the 1.9 databsae and 1.9 moodledata directory? Yes? In which case, you could modify the files in the old moodledata folder and update the whole site again to Moodle 2.x.
One further point, I found that you will need to set the "Media filter" setting for all the HotPots to "none". If the "media filter" is anything other than "none", then the HotPot module will remove the <object> tag that embeds the JGloss and replace it with a link to the JGloss page, along with text that says "Warning: rosa_gloss.htm could not be embedded." I think that explains why you were seeing that message sometimes.
all the best
