Problem with scrolling in IE

[anais]

Hello.

I have a problem with scrolling in IE.

I am developing a canvas for containing some children with different top. This canvas
can be bigger than its parent, so scrolling appears. When I add children, children's top
are ok. However, if any vertical scroll is made, the children's relative top is affected and they appear
upper/lower than they have to. I mean, when the vertical scroll is made:

* In most of browsers, children's relative top holds correct (their variation of top correspond
with the variation of scrolling).
* In IE, children's relative top became incorrect (their variation of top don't correspond with the
variation of scrolling).

I send an image of the problem. I have added a grid as background in the canvas. Children are the orange rectangles.

I am using smartgwt 3.1 and IE10 (it was already happening in previous versions)


Thanks in advance
