Mouse events problems with background image on IE

Description
I am using Dojo's function:
surface.createImage({width: mainWidth, height: mainHeight, src: myPicUrl});imageR.getEventSource().setAttribute('id', "IMAGEBACK")
On a layer, I try to add a background image, however, when I try to use path to draw on it, I found that this extra background image will mess up the mouse event listener settings.
In particular, when I draw on an image on firefox, using dojo, I press the mouse button (mouse down) to draw, and everything works fine.
On IE 6, however, once I put an image using surface.createImage, the mouse down does not work anymore, and it seems like the program doesn't listen / respond to the mouse down event. Instead, it just draw without mouse down. Once I put the image away (without using the surface.createImage), then the mouse down draw works.

Thank you. For future references: you can actually attach a file, and I mean an actual file --- see Attachments, Attach File button on this page above. It saves cut-and-pasting for you and me.

The test uses 0.4 branch. I am delaying it until 1.0 so we can have a chance to see if it works in 0.9.

No 0.9 test was submitted => the defect is closed.
Could you attach a simple file, which demonstrates the problem? It will speed up the investigation greatly.
