WinCVS incorrectly showing locally modified files

[Chuck . Irvine]

WinCVS version 1.2 is incorrectly reporting that cvs controlled files 
are locally modified. Interesting it only does this for some files and 
not others. To check out files, I'm using the version of cvs.exe that 
comes with cygwin (version 1.11). Any help is greatly appreciated. 
Thanks
