I have a workbook that now and again after running a macro (issue occurs with
many different macros) the first say five or six columns are covered in grey
so one cannot read the data below the grey. If you scroll to the right then
all those columns up to the end (IV) are visible as usual. If you change
sheets then the grey panel is showing on each sheet.

Any ideas to prevent this occurring will be very gratefully received
