OPOS -> VB.Net

People,

I realy need some programmers to think with me:

We written down a POS program, I'm using VB.Net en OPOS drivers from Epson but the system is realy going slow. When I scan a barcode the programs works fine but the customer display is slowing down my program. Can some one help me. I used the next programlines:

rcDisplay = Display1.Open("Display1")
rcDisplay = Display1.Claim(5000)
Display1.DeviceEnabled = True

If Display1.ResultCode Then
MsgBox("Customer Display Error")
Else
rcDisplay = Display1.DisplayTextAt(0, 0, "TEST", DISP_DT_NORMAL)
Display1.DeviceEnabled = False
rcDisplay = Display1.Release
rcDisplay = Display1.Close

End If
