lag time on new plan

[hobgood]

I am using X6 with the latest update installed on Saturday Feb 15. Drawing a floor plan for a church (18000 sq ft) 8" cmu ext walls, 3 5/8" mtl stud int walls, doors (slab), 4 toilet rooms drawn and room names. No roof and no foundation at this time. After the update I am getting a 3 to 4 second lag time on every move that's made. Any ideas?

Thanks Tim
