Dialog box

I am running the PC version of Steam within OS X. I have installed Half-Life.
Now I would like to install the high-definition pack. The way to do this is to
visit the link:

steam://installaddon/halflifehd

However, clicking on this link does not automatically send the click to Steam
(so whatever API is used by Steam to register steam:// to redirect to Steam.exe
is having no effect).

When I click on the above link, I get a dialog box within OS X (attached). From
within this dialog, I can select any OS X application (*.app) to receive the
steam:// click. However, if I navigate my drive_c directory, all Windows
executables, including Steam.exe, are gray and cannot be selected. Therefore, I
cannot redirect it to the PC version of Steam. (It's worth noting that one
could redirect it to the Mac version of Steam).

This is obviously a problem with Wine fitting into the OS X design paradigm.
But the program doesn't work as it's supposed to, so it's a bug.
