Categorize issue

I have a view with cca 8 columns. I want to categorize first two columns. If I do a categorize on first one, everything seems to be OK. (there is a twistie triangle displayed)… Afterwards, I make second column categorized. And if I click in the second column on a twistie triangle, sometimes happends, that the parent twistie in first column disappeared …

The scenario is like this:

In first column, there are names of Project Managers. In second column, there is a status of their project. (open,in progress, closed) …

If I click on the status twistie, for instance, the open categorie should hide, or unhide, but I still need to see the name of the project manager. But in my case, this name disappeared …

Where is a problem?

AAAA …

I have realized it!

It was just hidden, because after my click, the scroll bar has been added to the application. I did not noticed it before, so the behavior looked strange to me …

So it is solved …
