#30 Can't add test fixture to subdirectory

[Grim]

v 0.4.94d

When using the context menu on a sub-folder under a
project to add a Test Fixture to the project, the Wizard
never appears and instead I get the following error:

Specified cast is not valid.

Also, when I try to add a Test Fixture to the project in
the project directory, the specific class options boxes
both show System.__ComObject for all options, instead
of the libraries/classes that actually exist in the
solution. I don't know if this is an after-effect of the
previous bug or if it would happen also on a clean boot.

So far, in addition to these problems with a fresh installation
of this version, I have yet to be able to actually add a Test
Fixture to a project using the wizard.

Even if the wizard appears to complete, no class is added to
the project, and I return to page 1 of the wizard instead of the
wizard completing and closing.
