Gremlins in the background?
Hi, I was just after some thoughts please. When there's modules that have been deployed onto the LMS (having previously been tested and work) and out of, for example, 1000 people, have used it and have no issues, but, say 25, come back and say the module either freezes and won't let them progress or the drag and drop options won't click into place, what would the suggestions be to rectify this?
What could be the reasons as to why it works for the 925 people and not for the 25? Are there Gremlins that pick and choose who the 25 people will be that it won't work for? How can I "fix" something that isn't broken, if it works for me?
