Most likely you have 2 different versions of the treeview installed on your
computer. For example, on mine when I list the "Other Controls" I see:
Microsoft TreeView Control, version 5.0 (SP2)
Microsoft TreeView Control, version 6.0
The two can be from different Office updates, or from applications that were
built with an earlier version of the control so when the app was installed it
installed the earlier version even though the later one was there.

I noticed that the treeview control appears to have different properties
available to it depending on whether it's used within a form or sheet in
Excel 2003.

Apparently using an image list is not possible when the treeview control is
placed on a sheet rather than a form. Not only this, but the option to
display a checkbox for each node also appears to be absent when used on a
sheet too, and this appears to be only one of a handful of options that
aren't there.

Just look at the 'custom' property dialog for a treeview on a form then on a
sheet - there appear to be 3 checkbox based options on the 'general' tab when
placed on a sheet and 8 when in a form. The 'Full Row
Select','Checkboxes','SingleSel','Scroll' and 'Hotracking' options are all
absent on the sheet based treeview options.

I'm curious: why are there these differences?
