Can't open form in IDE when project opened from mapped drive

[MC]

Hi all,

I've read the various posts concerning file access on mapped drives--I
think problem is different:

The problem: Open a VB Winforms project from a mapped drive and all
files open fine except form files. Their code opens fine but trying
to open them in the form designer I get (for instance)

"The item 'MainForm.vb' does not exist in the project directory. It
may have been moved, renamed, or deleted."

However, if I open the same project without using the mapped drive to
access it, everything opens fine. I've already set the Intranet
security level for .NET to Full and I've done

caspol -security off

Until recently, I was successfully using Windows 2000, SP4, VS.NET
2003, Framework 1.1, and I was able to open projects located on a
mapped drive. I open projects very frequently and they are located on
a local drive, but *deep* in the directory tree, so I like to map them
to a drive letter. Recently, I went to a new machine, using XP Pro
SP2, VS.NET 2003, Framework 1.1, and I think opening projects on
mapped drives was working fine until I teaked something (I've been
trying to figure out what for a time now). I did a VS.NET repair, to
no avail.

I'd like to avoid reinstalling VS.NET, so I'm hoping to first get some
suggestions here.

Thanks!
Craig

Well, I think I've licked my problem, for those who are interested...

Remember subst? Good ol' subst! Seems to work just fine with XP and
SP2 (so far, anyway).
