vista bug

My program was developed for Windows 2000 and XP. It works fine on vista. But
there is a problem. It can not access Paradox database using DAO on Vista RC1
and RC2. The Paradox database can be opend, but CDaoTableDef::GetFieldCount()
always returns 0.

The problem must relate to vista UAC. If I run my program as Administrator,
the problem disappears.

I suspect this is a bug in odbcjt32.dll, which is ODBC Jet driver for
Paradox. This file comes with Windows. The version of odbcjt32.dll on vista
is 6.00.5600.00, on XP sp2, it is 4.00.6200.00.

odbcjt32.dll is protected by WRP, so I can not replace it with the XP
version - 4.00.6200.00. However I tried this way: rename the XP version and
modify registry to reference it, it worked. So there must be a bug in the new
version of odbcjt32.dll on vista.

Please help.
