Thanks David,
I knew I'd miss a few things. I've added a "patch data" segment at the end
of this email for those who want to manually update their v0.52 file. This
patch will also be uploaded to sourceforge tonight (I hope).

True for RE, but not true for MLE. The problem is that I removed the
scrollbar styles from the RichText control definition. This is a mistake
because it can break some existing code. I was trying to cater for those
people who wanted a RichEdit control that did not have scrollbars. However,
I've come up with an idea for this that I'll elaborate on later. Your
reference to MLE problems is because I changed the GENERIC.EXW code to use a
RichEdit during my testing and forgot to put the MleText back again.

True. But I don't know why. It is not receiving the notification messages
that I'd expect. Maybe Matt L. can help us on this one. At this stage I'll
just note it as a known bug.

True. This is a mistake. I did some last minute rearranging of some code
(via cut&paste) and forgot to change the variable name and didn't re-test. A
BIG mistake. Sorry.

I can change this if you guys/gals want it. But I figured that the
experimental code was not really meant to replace an offical release, and I
wanted to keep the download size as small as possible. So I only included
the files that had changed or were new. In fact, I'm considering releasing
patches as deltas to the source code files (I'm writing an automated
"patcher" program.)

True. This has been in the code for ages. I noticed this back in 0.45 and
coded a fix for it, but it never made this release. I'll make sure it gets
into 0.53 though.
