[softwarelist] Re: Ovation Pro for Windows (all recent versions) - How is the undo buffer size limit applied?

In message <0fgf03t82ls6gp8mffkg0j6dpl7smvgtlu@xxxxxxx>, Paul Witheridge <paul@xxxxxxxxxxxxxx> writes 
I am using a lot of graphics in the documents I am working on. I also
have the "Save Undo Buffer" option ticked in the Application Choices
with an undo buffer size of 128k.

I think that Ovation Pro for Windows must be ignoring the undo buffer
size, or perhaps just counting non-graphic data in the undo buffer.
For example, my document size just went from 171 MB to 91 MB after I
had first added another graphic and then created a table of contents
(which involved just text editing).

The largest graphic in my document is a 9MB .bmp and the total of all
the graphics is about 100 MB on disk. Some of them were added quite a
lot time ago (in editing terms). I can understand Ovation keeping
extra data in the undo buffer when I have been working with large
graphics, but why does it keep so many of them?
This is a question that has been asked since the start. OP puts references into the undo buffer. That means that a picture however large only takes up a modest space in the undo buffer - not quite four bytes but little more.
That's just how it works. I used to think this was a bad thing, today I'm not so sure, do you really want to push the undo buffer up to 20MB to retain the last picture and then end up saving a years worth of text edits?
Click on Min Memory (RISC OS) or Clear undo buffer (Windows) to get rid of things.
