It happens when I select "Settings" in the menu... and only "Settings." This doesn't happen in any other modules. The version of the Announcement module I'm using is 03.04.00. This happens regarless of the skin, including DNN Blue.
This evening, I did a fresh installation of 4.5.1... no additional content, modifications, or added skins/containers. I installed the Announcement module and placed in the left pane. I go the same results. BTW, it doesn't matter which pane I place it in.
I checked this in Firefox 2.0.0.4 and Opera 9.21 and examined the error consoles in each. Below is the best that could extract from them (including the IE7 message):
From IE7 - Line 944 Char 39
dnn_ctr375_ModuleSettings_valCacheTime.controltovalidate = "dnn_ctr375_ModuleSettings_txtCacheTime";
------------------------------------------------------------^
From Firefox - missing ; before statement
var dnn_ctr374_ModuleSettings_Settings.ascx_valHistory = document.all ? document.all["dnn_ctr374_ModuleSettings_Settings.ascx_valHistory"] : document.getElementById("dnn_ctr374_ModuleSettings_Settings.ascx_valHistory");
-----------------------------------------------------^
Firefox was able to point me to this line of code in the
dnn_ctr375_ModuleSettings_valCacheTime.controltovalidate = "dnn_ctr375_ModuleSettings_txtCacheTime";
