Summary:

Opening a custom URL in a new window may result in a script error in v7.2.

Symptoms:

A custom URL can be added to the main Find menu by nanvigating to Administration -> Advanced Customisation -> System Menus,and selecting the Find menu option. 
In order to have the URL open a website in a new window, you can select the customurl action, enter a URL (e.g. http://www.google.ie), and set the New Window option to Yes.

On testing this, you would expect the Google homepage to be opened in a new window. However, the new window is not opened, and a script error is displayed:

Script error:

Object doesn't support property or method 'SelectNewWin'
Do?SID=45279599335751&Act=523&Mode=1&CLk=T, line 1 character 33

Workaround:

Enter a custom URL in the following format:

javascript:SageCRM.webMenu.SelectNewWin('http://www.google.ie');

where http://www.google.ie is the site you want to visit.

You'll need to set the New Window option to No, or blank it.

Resolution:

This issue was introduced in v7.1, and was resolved in v7.2b.
