Problems with Apple HFS+ driver in BootCamp 3.1

I got a newest MacBook Pro with Snow Leopard recently on which I reinstalled Boot Camp 3.1 with Windows 7. I was running Leopard with Windows XP previously.
The latest BootCamp version provides read-only access to the main Mac (HFS+) drive. I ran into multiple problems in using this drive (F: in my case) within just few days of working with this setup. Here is the list:

1. Many .EXEs can not be executed at all from the drive. Windows gives "Could not find file" error even though the file could be copied just fine. I could not figure out the pattern, but, about say 90% of .EXEs could not be executed.
Test case: Run wrar393.exe ( http://www.rarsoft.com/download.htm).
2. robocopy utility crashes when source directory is on HFS+. copy and xcopy work fine only in PowerShell.
Test case: PowerShell> robocopy F:\Library\ColorSync\Profiles\Displays $env:TEMP
3. Command Prompt (cmd) crashes or gives "the parameter is incorrect" message on any dir command, copy and xcopy, etc. Overall, Command Prompt seems to be unusable. One time I got a Blue Screen of Death in this scenario.
Test case: cmd> dir F:\Library
4. Rounds up file sizes (for example, in Windows Explorer) to a cluster (x 4Kb) size. This is annoying and could be an issue for file synchronization. If a file is copied locally, it will come up in a correct size.

Do you run into the similar issues? Any solutions? Does anybody have a better luck with third-party HFS+ drivers, for example with Paragon HFS for Windows ( http://www.paragon-software.com/home/hfs-windows/) which is currently free?

MacBook Pro (15-inch, Mid 2010), Mac OS X (10.6.3)

Rename AppleHFS.sys and AppleMNT.sys

By doing the following you will disable HFS mount / read mode on windows XP, Vista, 7.

Navigate to c:/windows/system32/drivers/AppleMNT.sys, rename the AppleMNT.sys file to something like AppleMNT_keep.sys or something of your likings.

The faulty HFS driver is a valid concern. It seems to happen on many systems.
You find it in Windows/system32/drivers/ AppleHFS.sys

Renaming to AppleHFS_disabled.sys will avoid the blue screens until you have found another solution or Apple updates Bootcamp 3

----
After renaming both myself because they are no longer "*.sys" or something? they are gone. In my case AppleHFS prevented Windows Backup from running to end and was causing error "some files skipped" and while some might find reading convenient, I prefer Windows not have even read-only access.

You can probably do better with MacDrive8.

I had a success with Paragon HFS for Windows 8.0 Beta (it was free because it's beta). It solves all the issues, and also provides read/write access. I did have one blue screen of death so far while running robocopy, but it does not seem to be a repeatable problem. I did have to go through Paragon support to resolve the installation issue. Apple HFS service had to be stopped after Paragon driver is installed. Other than that, everything worked fine.

Just a dumb question. You say "Apple HFS service had to be stopped", but I find no such service on Win7. There IS an AppleHFS.sys driver, so do you mean you did the rename trick mentioned above?

Does Paragon really allow use of the Mac partition from the command line? I REALLY don't want to keep a copy of my MP3 library in each partition.

1. Sorry for confusion, Apple HFS is apparently not a service - probably a device. It was stopped via a registry change, and I did not really check the list of services:

[HKEY LOCALMACHINE\SYSTEM\CurrentControlSet\Services\AppleHFS]
"Start"=dword:00000003

2. Paragon driver will mount a drive letter for full use, including cmd and PowerShell. It effectively replaces Apple driver. MacDrive does the same.

I have to say that I experienced one system freeze while copying files via robocopy. Not sure whom to blame. Other than that - everything works great.
