You cannot use the "Minimize" option and other menu options in Web Parts in the personal view on a Windows SharePoint Services site

You cannot use the Minimize option and other menu options in Web Parts in the personal view on a Microsoft Windows SharePoint Services site.

This issue occurs because the default value of the AllowPersonalization attribute is set to "false" for the WebPartZone in the Default.aspx page on the Windows SharePoint Services site.

To resolve this issue, set the value of the AllowPersonalization attribute to "true" in all Web Parts of the Default.aspx page that has the custom portal site definitions. To do this, follow these steps:

1. Open the Default.aspx page of the site definition from an editing program.
   
   For example, you may find the Default.aspx page in the following location:
   C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\TEMPLATE\1033\Custom Site Definition Folder
2. Locate the following tag in the Default.aspx file:
   <WebPartPages:WebPartZone … />
3. Set the value of the AllowPersonalization attribute to "true" as in the following example:
   <WebPartPages:WebPartZone AllowPersonalization="true" …/>
