On one of my PCs when i run a subroutine via a command button, i am then unable to key in data into some cells. No error message comes up - I can select the cells, but it's as if the keyboard isn't working, but only after the VBA code is run. This is only an issue on one PC. All PCs running windows 10, excel 2016, exact same excel file. Problem pc has a second monitor. Please help!
