If you create a web part page in MOSS 2007 it won’t show the Quick Launch on the left side of the page.
To work around this open the page in SPD and remove the following code:
<asp:Content ContentPlaceHolderId="PlaceHolderLeftNavBar" runat="server"></asp:Content>
Unfortunately, the Quick Launch won’t be the correct width so in order for that to be displayed correctly you need to remove these additional lines of code:
<asp:Content ContentPlaceHolderId="PlaceHolderPageImage" runat="server"></asp:Content>
<asp:Content ContentPlaceHolderId="PlaceHolderNavSpacer" runat="server"></asp:Content>
