window.open弹出的网页不到两秒自己关了?怎么办?

{
int iIdx = Convert.ToInt32(e.CommandArgument);

Response.Write( " <script> window.open( 'SendFileNew.aspx?id= " + sLiuShuiID + " ') </script> ");

string sPath = dt.Rows[0][ "附件 "].ToString(); // 如果有附件
if (sPath != " ")
{
sPath = Server.MapPath( "~ ") + sPath;
Session[ "AttachmentPath "] = sPath; // 暂用Session传

PrintAttachment.aspx的page_load事件里有:
string sPath = Session[ "AttachmentPath "].ToString();
FileInfo DownloadFile = new FileInfo(sPath);
if (DownloadFile.Exists)

Response.ClearHeaders();
Response.Buffer = false;
Response.ContentType = "application/octet-stream ";
Response.AppendHeader( "Content-Disposition ", "attachm
