Issue with Clipboard operation

I am using DHTMLX in a WebLogic iPortal environment where we design multiple portlets in our portal.

I come across an issue using block copy in Clipboard operation where the overlay highlight is off from where the data you select. Please see attached image


.

I feel there is something to do with dhtmlxgrid_selection.js where it specifies event XY position.

Has anyone come across similar issue?

Thanks in advance.

Normally , the selection is created inside grid area, so such error is not possible.
But if you have some custom css styles on the page, which has removed position:relative, which was defined in dhtmlxgrid.css

div.gridbox .objbox {
background-color:white;
position:relative;
}

then situation similar to the above one may arise.

Stanislav,

You are right. The position:relative was removed by some custom css. When I place the above css into my page directly, it was able to display the overlay color correctly.

Thanks,
Brian
