Auto Clean Up Wire does not work well

[alii001]

Auto Clean Up（CTL+U）is very useful, but in some case this function seems a little strange.

1\When I select nothing of the diagram(clean up the whole diagram by labview's default settings),and press CTL+U, it does not work , no any movement of the diagram. I know some parts of the diagram must move if the Auto Clean Up works, but it didnot .

2\When I select parts of the diagrams, for example ,there are 3 WHILE loop , and I choose one(click the WHILE loop's edge line) , the select part can do Auto Clean Up,but other 2 WHILE loops become a little in a mass and become worse. For this reason , I can not finish solving one problem only to find another cropping up.

3\ In some case , though my VI seems out of order, it can run, after I press CTL+U,things become even worse, some error appear ,the VI can not run .

Is there an detailed instruction of the use of CTL+U?

Well, the usual detailed instruction is: don't use it.  Instead, learn to lay out your VI in a readable way in the first place.  I always say, "If your block diagram looks nicer after using the cleanup tool, you're not doing it right".

There are still problems for me to properly use LaBVIEW about the CleanUP function.see the flash above and below

Any help will be appreciated.
