backspace issue

Hi

iam using dhtml grid.In the columns of grid backspace is not working.If i enter some value in the cell and i clicked on backspace button,it is not working.For deleting the value i have to select it and then pressed delete key.why backspace is not working for deleting value.Those columns are in edit mode.It occurs for all column types.Iam using dhtmlxGrid v.1.5 Professional edition build 80319 version

The issue still can’t be reconstructed locally, the same build of grid works correctly with backspace key.
Please contact us directly at support@dhtmlx.com and provide your ref. number - we will send you an updated for dhtmlxgrid 1.5 which may resolve issue.
Also, if it possible - please provide any kind of sample where problem can be reconstructed.
