When you design a form and see the preview on google chrome and firefox is ok, but when check it on IE9 and all the form is broken. This happend on ZK 6.5.2 but not on 6.5.0.

Screen attached.

.zul code:

<window >
<grid width="500px" >
<rows>
<row spans="35%,75%">
<cell>cell_1 – 35%</cell>
<cell>cell_2 – 75%</cell>
</row>
<row spans="40%,60%">
<cell>cell_1 – 40%</cell>
<cell>cell_2 – 60%</cell>
</row>
</rows>
</grid>
</window>
