IE doesn't immediately reclaim memory; it will actually keep going up until it
'decides' to reclaim the memory and will then reclaim it. I did a bunch of work
around memory leaks and I don't believe there are any, though there certainly 
could
be new ones.

The C++ exception I'm worried about. Can you do me a favor and get exact version
strings for XP, IE, and Flash? Also, do you have Microsoft Office installed or 
any
other Microsoft products such as IIS? These sometimes change the core 
components of
IE during installation. Are you on a 64-bit platform?

What version of IIS do you have installed? That might be the culprit; I'm sure 
IIS
has reached down into Windows and changed some of its guts, affecting IE. Also, 
can
you attach the specific HTML and SVG file that was causing the issue?

I've experienced similar memory increase on IE7, however a good news is, IE8 
seems
don't have this issue, the memory holds still as I refresh page on IE8.

Attached is a sample I used to reproduce this bug. It creates a <svg>, draw a 
rect,
destroys the <svg>, repeat 30 times. You can observe memory increase about 4MB 
with
every redraw.

I think there are several different bugs here.

In terms of @young4chongs comment, every time you create and then destroy an 
SVG a
Microsoft Behavior gets created in the background. A known limitation is that
Microsoft Behaviors are never removed from memory even when deleted from the 
page:

http://support.microsoft.com/kb/309170

However, I've long wanted to simply recycle old Microsoft Behaviors that are 
removed
from the page, which means that you never reclaim that memory but at least it 
doesn't
grow over time as you create and destroy SVG images if the number are roughly 
the
same over time.

The other things on this bug I believe are separate issues not related to
@young4chongs issue.

BTW, just to be clear, Microsoft Behaviors _are_ reclaimed when you leave the 
page;
it's just when a page is just sitting there over time without a refresh.

I think this is no longer issue. In terms of Microsoft Behaviors increasing 
memory _while the page is 
loaded_, that is something we can't really work around. Marking Invalid.
