I would like to execute 2 macro´s at the same time. Something like
this:

Private Sub SimulationStart_click()

Do Until Range("B14").Value 1.2
Call ProcessCalculate ' runs calculations in the workbook.
Call LabelChange ' runs on a userform.
Loop

End Sub

The macro Processcalculate takes about 15 seconds to reach the value
1.2.

It seems that the macro labelchange executes when processcalculate is
done =(

Does anyone has an explanation for this?
