Some kind of memory leak bug under IE8

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call a small function that draws on the surface something simple. (every
100ms is good enough).
2. see how's the FPS falls down after a few seconds. and cpu load raises
from 10% to almost 100%.

What is the expected output? What do you see instead?
stable cpu usage (and low...)

What version of the product are you using? On what operating system?
windows 7

Please provide any additional information below.

results were the same on your pc.

ExCanvas uses VML elements. Since you are never clearing the canvas it will 
keep 
adding elements which will make it use more memory and make painting slower.

If you add a clearRect(0, 0, width, height) in there you should not see any 
memory leaks 
or performance degradation.
