W2G entry very slow

 I have several W2G’s to load. Each one taking over 20 minutes.  You click on the first box then have to wait several seconds before you can enter any data, then allows the next box to be entered, then locks up again when you click the next box.  I have cleared cache and even did Windows clean up.  All updates are current.  Even tried to unplug from Internet to see if it was sending data.  Any one else with this problem?
