Yes, Issues with the transparent panel.
In my application, user had the ability to add/remove dimension and keyfigures.
When user removes few key figures, the crosstab becomes small, and there is a transparent panel on top of the crosstab. because of that not able to use scrollbars to see complete data.
Ex:
Crosstab set to Width 500, and Transparent Panel set width 400 and placed on top of the crosstab
When user removed some keyfigures at runtime, crosstab width will become 300. vertical Scrollbar is under the transparent panel.
