Kalle posted up on his blog/FAQ this nice little tip that you may want to try out. You can use desktop standards policy maker to create an adm template with this setting in. Please also bear in mind http://support.microsoft.com/kb/931247/en-us - Description of the SoftGrid Client 3.x registry entries which are the supportable registry keys.
Did you know that you can remove those "Refresh Applications" and "Load Applications" from SoftGrid Client's context-menu (in version 4.0 and upwards)?
Visibility of these options are controlled by two registry values, found under HKEY_LOCAL_MACHINE\SOFTWARE\Softricity\SoftGrid Client\CurrentVersion\CustomSettings key (this key does not exists if you haven't selected option to hide presence of client using Properties->Interface in Client Management Console):
Setting value data to 0000001 (or omitting the whole value in key) makes selection visible, setting value data to 00000000 hides the selection.
