Dear Glenys (and other JGloss fans!)
thanks again for uploading your Elephants JGloss quiz to my server. I confirmed the flickering screen phenomena on FF 2 (Mac) and FF 3 (Mac) and modified the QuizPort module scripts to fix the issue.
FYI, there was some JavaScript in the HP ShowElements function which had a special workaround for an alleged bug on FF (Mac). There is a comment in the JavaScript which says ...
// FF on Mac bug : doesn't redisplay objects whose visibility is set to visible
However, this issue does not seem to apply anymore, so I have programmed QuizPort to remove the following two lines of JavaScript which only affect FF (Mac) and which were causing the flicker.
if (C.mac && C.gecko) {Els[i].style.display = '';}if (C.mac && C.gecko) {Els[i].style.display = 'none';}
The modified scripts are in the latest QuizPort zip file. Please download and install it when you have time.
best regards
Gordon
