Sage 100 2016 Can edition 20.4.4.41 - Slow grids in 11-2 and 5-5-1 - not responding

Ever since I performed the version change I have been experiencing very slow grids in 11-2 and 5-5-1 (daily payroll entry). There is a 2-3 sec delay in tabbing across the grid columns to the point where it actually says  it is NOT-RESPONDING!! Really annoying when you have a stack of work to do. It seems to be only my work station and everything else on my computer works fine. It is just in the grids when it is SUPER SLOW.  Can anyone help?? I tried tech support and my own IT guy and neither could offer any assistance.
