Hi,
Firstly, many thanks for PQGrid, it's fantastic.
I've found a minor issue with horizontal scrolling when virtualX is true.
My CSS has a 1px border on the pq-grid element.
In _setInnerGridHeight, the calculation of "ht" is using "this.element.height()", which is taking that border in to account every time it is called. That was adding 2px (one for top, one for bottom) to the height of the grid every time I scroll.
I've removed my border and all is OK now.
Just thought you should know!
