Well, it *is* kinda that way. The problem is that the cache doesn't know
if an app modifies a file deep down the tree. And until the shell asks
for the status of that particular modified file (i.e. if you show the
file in explorer), the cache doesn't check the file again (the status of
that file is in the cache).
So the problem is:
- the cache does not time out anymore
- the cache only checks the filetimes of those files the shell directly
asks the status for (imagine it would do that every time: the cache
would be useless because it would have to check every file every time!)
- an app modifies a file which isn't visible in explorer
- the cache doesn't know that the file has been modified
--> the wrong recursive status is shown.
But: you can run "cleanup". After the Subversion 'cleanup' is done, TSVN
then invalidates the cache down the tree of the selected 'cleanup' item.
The problem only exists when other apps modify files. Operations in TSVN
don't have this problem because TSVN notifies the shell about each
change and also tells the cache directly.
Oh, and it's only a problem if an app modifies a file *without* calling
the ShellNotify() API.

I've reverted the change which caused that problem already. Should be
gone in tomorrows nightly.
