Rolling revisions forwards and backwards, very stuck!

I'm trying to track down a behavioural error that has crept into our project.

Since I'm not sure how long the error has been around, I've been
reverting my working copy back to various revisions to find where the
bug crept in, and hence find the cause of the problem!

However I'm finding it really tricky to roll back my project, and then
incrementally add revisions back on.

So, I've used SVN->Show Log. Right-clicked on about 200 revisions
earlier, and selected "Revert to this revision".

Fine, the bug is now fixed. (It's a visual bug occurring only in IE6
during Javascript so it's very hard to pin down, or even test without
actually looking at the result).

Here's where I'm stuck. I want to roll forward an arbitrary number of
revisions to see where the behaviour has broken.

I've tried selecting a revision further up and "revert to this
revision". This appeared to attempt to revert a HEAD working copy back
to this other revision; but my working copy is no longer HEAD so this
produced a host of conflicts and other problems. I also tried "update
item to revision". That didn't seem to do anything.

So I tried a different approach: right-click my repository and select
SVN->Update to revision. This also seemed to assume I was still on a
HEAD copy, and also messed up my working copy.

Additionally, I can't just "revert" my working copy to get back to
HEAD, because this fails to delete a load of files that used to be in
the project and were re-created during my initial revert.

Can anybody give me a general idea of what these various menu options
are intended to do, and how I should approach my current situation?

Best regards,

Pete Hurst
