Helen2000 I don't work for Microsoft but I thought I would try to help you narrow down the cause of your "latency" problem. Are you using the desktop version of Microsoft Whiteboard or the version you access through a browser? I would recommend try doing the same thing in both the desktop version and the browser version to see if you have what seems to be the latency problem in one application or the other or both. I personally don't seem to be having a latency problem when I use Microsoft Whiteboard. There could be many reasons you are seeing what seems to be a latency problem. Also I would recommend trying to do the same thing in Microsoft Whiteboard at home that you are trying to do at work. Try it on different computers. Your work computer, home computer, laptop. You may discover that you only have the problem on one particular computer or you have the problem at work but don't see the same problem when you try doing the same thing at home. If it works fine on every computer accept the one you use in your classroom you may have a problem with your computer. If you are having the problem with every computer at work but it works fine at home then you may have a network bandwidth issue at your work location. If the app is slow but the browser version works fine that might indicate you have a local problem of some sort. If this is truly a Microsoft issue then you should see the same latency issue no matter what computer you use or what location you are at or if you use the desktop application or the browser version. If you see the latency at work but not at home then I would check with your IT department to see if they can determine that you have a computer problem or network issue local to your work. If it is a computer or network issue I doubt Microsoft would be able to do anything to overcome that issue.
