SourceSafe buttons on VB5 toolbar

In the VB5 SP3 development environment, under the “Tools” category on the “Command” tab in the “Customize” dialog for the toolbar, the “Check In”, “Check Out” and “Undo Checkout” buttons are listed.

When I click on one of them and drag it to the toolbar, an icon appears with the little “x” in a box. When the icon is positioned over the toolbar, the little “x” changes to a “+”. All this is as it should be. When the icon is dropped on the toolbar, however, no button appears.

FWIW, my machine is running Windows 2000 SP4.

Is there anything I can do to get the buttons to show up on the toolbar?

TIA,

Al
