border on ie7

Hi, i’m using a grid to show some data, everything works great but the bottom border is not visible on ie7, on firefox is visible. I was using dhtmlxTreeGrid_v14_Pro_70813, but then i upgraded to dhtmlxTreeGrid_pro_v14_71022 and the problem started. I tried with different skins with same results. Please help

Thanks in advance

Is problem occurs in standard samples or only with your code?
There was no serious changes in styling between two mentioned builds, and we not able reconstruct mentioned problem with local samples ( please be sure to use both css and js file from the same package, mixing files from different packages can cause problems )
In second case - please provide any kind of sample where problem can be reconstructed - you can send it directly to
