In another forum (http://moodle.org/mod/forum/discuss.php?d=41886#193503) there is lots of discussion about this problem. So I was hoping that with IE7 or Moodle 1.6 the problem is not there anymore. But in any combination I still have this problem. Only in (df)wiki. I did not experience the problem in another source or activity.
This is what I wrote in the forum mentioned above:
In a testing environment with a very recent 1.5.3+ version as well as 1.6 beta3, both with the latest dfwiki (that is called wiki now, version 2006042001) and using the standard theme I still have this problem with IE6 and also with IE7 beta2. Firefox gives no problems but my students only can use IE6 at school.
I hope this nasty problem is solved very soon within Moodle. I don't think that Microsoft is willing to change IE for it.
Can anyone help? I like wikis very much but this problem is to big for me to use them for studentactivities.
