Problem with recursive cvs edit command

[Dan]

OK,

I'm new to cvs, and think I've got everything working except for one
peculiarity.

I've got a modules file that looks like:

moduleA -d moduleA path1/moduleA
moduleB -d moduleB  path1/moduleB
AllModules &moduleA &moduleB

I then checkout AllModules and end up with a directory tree locally like:

AllModules
    moduleA
    moduleB

which is what I would expect.  I can commit, get status, get logging, etc.
at any point in the tree and everything works just fine.

If however I do a 'cvs edit' on moduleA, and moduleA has sub-directories
(let's say suba for example - which has a file in it called filea), then I
get the following error:

cvs -z9 edit (in directory C:\AllModules\moduleA)

cvs [edit aborted]: cannot find suba/filea: No such file or directory

*****CVS exited normally with code 1*****

If I do a 'cvs edit' on 'suba' directly however it works fine, and all the
files in suba are marked edit:

cvs -z9 edit (in directory C:\AllModules\moduleA\suba\)

*****CVS exited normally with code 0*****

Any help for this novice cvs user would be greatly appreciated.
