TypeMock reference <HintPath> is relative, not absolut

Hi, unlike most other assemblies that are referenced by a Visual Studio project from the GAC, TypeMock adds a <HintPath> tag to the project references, e.g. -

for nunit -
<Reference Include="nunit.framework, Version=2.4.0.2, Culture=neutral, PublicKeyToken=96d09a1eb7f44a77, processorArchitecture=MSIL" />

but for TypeMock -
<Reference Include="TypeMock, Version=3.7.1.0, Culture=neutral, PublicKeyToken=3dae460033b8d8e2">
<SpecificVersion>False</SpecificVersion>
<HintPath>........Program FilesTypeMockTypeMock.NETTypeMock.dll</HintPath>
</Reference>

If the project is then moved to another location on the same drive, the reference will be broken. Why does TypeMock not work the same as other applications, or at least write an absolute <HintPath>?
(actually, if the project is on another drive, TypeMock does write a absolute <HintPath>)

Thanks, John.
