I'm facing a layout problem with IE9.
On a certain page I'm developing, there's a side menu bar with CSS property overflow-y: auto so that a scroll bar appears if the content in the menu does not fit the part defined for it. The behavior occurs correctly in all browsers. The scroll bar appears above the menu bar in the right corner. It happens that in IE9 browser, when the scroll bar comes up, the width of the menu bar decreases considerably, causing a line break in some menu elements.
Does anyone have any idea how to solve this problem?
