how much memory does your developer machine have?
I find VS2010 is very resource intensive; a single isntance devenv.exe is currently 1.4 gig or ram for a big project, and two others are using 464K and 304K, respectively.
when i run low on ram, and stuff starts getting swapped to disk, i've seen VS2010 start getting buggy, reporting fake errors, refusing to build even when there was not changes, and worse;
the solutions been to close VS and reopen again, letting it creap back up to huge memory reserves, where i have to rince and repeat.
my machines not a wimp either; 4 gig of ram's not a horrible developer machine.
