Hi All, Below is from an issue sent to Support and they were wondering if anyone in the User Community had everseen this. Thanks for any input I can pass back to them. Chris "We want to customize the popup window of the field Assignee To of tab Action Item (project) to include additional fields in the column list and the filter for the 'Resources' tab. We want to modify this browse window without changing the source code. If we cannot modify the existing window, can we create a custom field of type browser with our additional fields, which will open a new popup window with multiple tabs as it looks today but with our additional column and filter fields? If yes, can you tell us how to replace the existing browser field with our new custom browser pop-up window/field? "
