Windows 7: Visual Studio 2008 Issues

I apologize beforehand if this is the wrong place to post my questions. I posted them over in the VS setup and install forum on MSDN and they said it was off-topic and to come here??? Anyway, thanks for any help anyone can give me...

A month ago or so, I updated to Windows 7 Pro. Everything else I've left the same, so I almost have to think it's something to do with Windows 7. I've noticed a couple very annoying issues...


1. VS randomly decides to edit my main .csproj file. Sometimes it does nothing to the file. Other times it will edit it and either make no changes or it will re-order things. In the situation that it does edit the file, this causes a checkout from source control (SourceGear Vault) and puts an exclusive lock on the file. I'd like to figure out how to make it not check out the file unless I make a change that requires it.


2. I have a problem with one particular class library in my solution. I find if I either change a file in this project and do a build, or if I change a file in another project and do a rebuild, I get an Unable to copy file "obj\Debug\EVE.BusinessEntities.dll" to "..\..\..\Bin\Debug\EVE.BusinessEntities.dll". The process cannot access the file '..\..\..\Bin\Debug\EVE.BusinessEntities.dll' because it is being used by another process. This then requires that I restart VS. The process that has it opened is devenv.


I have no idea what to look at for my problem #1. As for problem #2, I saw suggestions of changing Copy Local and that using a common output directory would cause it. I played around with some of the fixes I saw and none seemed to work. Plus, I find it hard to believe those things could be the problem since my old XP install (and the XP installs of my co-workers) will build this thing fine.
