Edit Group Popup does't show current Context

When editing a group using the popup dialogue box "Edit Group XXXX", The group function from ajaxCb.php does not populate the context drop down list. (updates work fine)

Looks to be due to myContext (var) not being initialised during the initial SQL call.

/*Added new line in groups area of ajaxCb.php at line 404 to initialised the myContext variable to the correct value*/
$myContext = stripslashes($row["Context"]);
