Trouble getting subclipse to recognise files under version control

Hi all,

Sorry for the length of this message, but I wanted to
provide as much info as possible, since I have no idea
of what is going on...

I have been using svn command-line to setup & test our repos
but now that we are about to start rolling it out I am using
subclipse more. I had tried subclipse during initial testing
and it worked fine; however now I am running into a bizarre
problem - I can use subclipse to check out a java project, but
then eclipse doesn't recognise that the files are under version
control - either it shows "?" decorations or no decorations
and under the Team-> submenu it either enables only the "Add"
type options or else only shows the Share/ApplyPatch options
(although the .svn dirs are all there & TSVN does recognise them).

Yesterday I installed a fresh copy of Eclipse 3.0.1 (Build id: 200409161125)
and used the "Software Updates" to install site.0.9.31.zip locally
(I had the same problems using 0.9.30, so I don't think it is
to do with the change from subversion 1.1.4 to 1.2).

I have tried a number of ways to co a project from subversion 1.1.4:

1) From SVN Repos view, choose the folder/module and "co as ... java proj"
    "The resource already exists in the workspace and will be deleted. Proceed?"
    OK -> Files co, .svn created, TSVN recognises, eclipse says "?"/"Add",
    project title shows "title []" (nothing between square brackets)
    .svn dir appears in Eclipse resource view
2) svn co from cmd-line into a tmp dir and then import from filesystem into proj
    Files copied with .svn, TSVN recognises folders but not files, Team->ApplyPatch
    project title shows "title" (NO square brackets even)
    .svn dir appears in Eclipse resource view
3) svn co from cmd-line into workspace and then create a proj with same name
    then choose ShareProject which says "Module already exists remotely.
    Would you like to sync local proj with existing remote module?"
    Choose "Yes" which then says "No changes found"
4) "svn co" (i.e. without bringing up dlg to choose type/name/etc.)
    a) one exception in workspace/.metadata/.log when I pressed cancel btn:
!ENTRY org.eclipse.core.runtime 4 2 Jun 02, 2005 11:30:13.04
!MESSAGE An internal error occurred during: "SVN Checkout".

        at org.eclipse.core.internal.jobs.Worker.run(Worker.java:66)

    b) another (different) exception when I didn't cancel...
!ENTRY org.tigris.subversion.subclipse.core 4 4 Jun 02, 2005 11:49:48.715

        at org.eclipse.core.internal.jobs.Worker.run(Worker.java:66)

The only other thing I see in workspace/.metadata/.log is (the second msg
"cannot find path" is repeated every couple of seconds
- I think it only arises from the "import from filesystem" case):

!ENTRY org.tigris.subversion.subclipse.core 4 4 Jun 02, 2005 10:32:24.507
!MESSAGE Project {0} does not contain SVN folder meta-information.

svn: Can't open 'C:\Richard\eclipse\workspace\shenix3\grub\.svn\tmp\menu.lst.tmp': The system cannot find the path specified.

Sorry for going on so long, but we are just about to roll this out,
so if anyone has any suggestions on what may be wrong or where
I could continue investigations I would be very grateful.

Thanks in advance,
Richard.
