IE crashes when try to open document from SharePoint 07

Issue:

This happens when Office 2003 installed along with SharePoint Designer – a 2007 product.

This problem occurs if the following conditions are true, in the order in which they are presented:
- You install a Microsoft Office 2003 product on the computer.
- You install one or more 2007 Office system programs on the computer.
- You repair or update the installation of an Office 2003 product.

In this scenario, the older version of the Name.dll file becomes the registered version. When the Owssupp.dll file is used, it tries to use functionality that is not available. This condition causes Internet Explorer to crash (stop responding).

aRTE asking for password

Problem:
I have installed ARTEEditor for Sharepoint (MOSS 2007). For the site collection administrator user there is no problem using ARTEEditor, everything works fine. If any other user (Wiki Member = Contribute or Wiki Admin = Full Access) tries to edit the wiki page, ARTEEditor opens a login window and keeps asking for user/password, eventually failing.

Solution:
This error occurs when the ARTEeditor folder does not have the same permissions as the SharePoint Group your Site Collection Administrator is a member of. Navigate to the ARTEeditor folder within the Virtual Directory folder on your server that relates to your SharePoint application, right click to bring up the properties of the folder and make sure that the following groups are added under the security tab:

ADMINISTRATORS
WSS_ADMIN_WPG
WSS_WPG
IIS_WPG
AUTHENTICATED USERS (of the server with only Read permission)

And any other members or groups that are specific to your SharePoint application.

Sharepoint designer Server Error: Access Denied

Try adding your user account to the “Policy For Web
Applications” screen. To do this, log in to Central Administrator and
select the Applications tab. Click “Policy For Web Applications”.
Click “Add Users”. Choose the right web application and All Zones.
Click Next. Choose your user account and make sure it resolves using
the People Picker. Give the account “Full Control” and click “Finish”.
You should be able to check files in and out using SharePoint Designer
without that annoying error message! Hope that helps
