Gigaixel 7.2.0.0 please disable the filter upscaling by resize output factor 1.00

Version 7.2.0
When i set the resize mode on output factor 1.00 then must to be disable the filter “upscaling” . It run and run endless by a picture of 1600x2800px for upscaling by factor 1.00 and when to be changed anything (only the position of preview-picture) , it will to be run renewed. Factor 1.00 does’nt upscale, therfore nonsense.

Who should to wait so long for processing of one picture ?
