Updated a few machines to 1703 and had some issues with Sage100 2016 being laggy. Windows would take 5-10 seconds to close or open. I then rolled back to the previous build and all was fine again.
I guess just an "FYI". Anyone else seeing this issue?
We have a client with the same issue, so far no fix other than rolling back.
Make sure the clients have all updates. I'm still using 1703 on my machine and after a few months of updates, this issue resolved.
