Hi Glenys,
as far as I am concerned, your feedback, comments, ideas and suggestions are very important and very welcome. Please keep them coming!
I found a tool which looks like it might be useful for testing IE:
I don't endorse it or particularly recommend it, so use it at your own risk, if at all. I tried it on my PC and the "Edit quizzes" page in "Custom corners" theme seems to display OK now in IE6/7 with the modifications to CSS that I recently made.
best regards
Gordon
