403331 display errors joomla website

Hello, I have some problems on this website when use IE to navigate it, most of this doesn't happen when using Firefox. The site is based on joomla 1-As you position the cursor in the main menu an error mark in the status bar, seems to be a problem with the menu module, you can change the module keeping the appearance. 2-On IE 8 search box is misplaced, and modules are mixed up 3- some of errors on 2. doesn´t happen in compatibility mode, but but the gallery fails (error on page) 4- after password change process, It messes up the user entry form and other modules positions (both in mozilla as in explorer). 5-when entering the wrong password there is no apearance change, do it more friendly. 6-When registering a new user we need to display a message please check your e-mail to continue the registration process (nothing comes out so people can not activate the account.) 7-Add an option to logout visible so users can exit safely. It should display the same way both on IE and Firefox thanks, please check http://www. c n p-c o l o m b i [login to view URL]
