GXT Grid's Columns menu disappears in IE 8 when the grid has around 70 columns

[skmd]

Hi

We are using GXT 2.2.4 and IE 8.

We have come across an issue while working with the GXT grid that has approx 70 columns in it.

Step to re-produce

i) Create a GXT grid (used the Remote filter grid same code from GXT showcase )
ii) Create around 70 columns (Most of them are hidden initially).
iii) Run the application in IE 8.

When the grid is displayed, click on the column header icon. The menu that pops up with the option to sort, hide, and filter shows up for a second and closes immediately.

We have tested this code in IE 9, Chrome , Firefox and Safari. In all of these browser the functionality works correctly. But fails in IE 8.

I have attached the files of a sample project that demonstrates the problem when the app is run in IE 8 browser.

Please let me know how to fix this issue. Your reply would be greatly appreciated.

Thanks,

We are in the process of evaluating the purchase of Ext GWT and were wondering if there are any thoughts to alleviating this behavior?
