Macros are great for doing the mundane (or not so mundane) processing that is often necessary with Excel data. After you start to use them, you may find that running macros can consume quite a bit of time. While you are running them, there is very little else that you can do, since Excel won't allow you to do any other work while the macro is chunking away.
The best way to do additional work is to open another instance of Excel. As you are working on one workbook in the foreground, the other instance of Excel continues to work away at the macro in the background. This approach works because Windows allows multiple instances of a program, each in its own workspace. The only thing you cannot do is work in the foreground on the same workbook which the macro is using.
In order to open a second instance of Excel, simply follow the steps you followed to open the first instance. For example, if you started Excel by calling up the Start menu and then the Programs submenu, you could do the same thing to open the second instance.
You should realize that the macro running in the background instance of Excel will be affected by you working on a different instance of Excel in the foreground. This, again, is related to how Windows treats different programs. On most systems, the background programs are given a smaller percentage of the CPU's attention than the foreground program.

Put a "Doevents" instruction in repetitive loop(s) and long routines allows Excel to respond and allow you to work on other workbooks or even the same workbook that the macro is running.
The consequences are that the macro will run more slowly/take longer to complete, and for the user E cell will be less responsive.
Working on the same workbook in which the macro is running can have issues if the user changes things that the macro is already changing or wnose value the macro acts upon.
