It means an external application is attached to Cube, "reading" the UI. When there are a lot of controls visible (for example a big table), this can have an impact on performance.
Cube does not know which application is attached.

If you have a touch screen, it may be TabTip.exe (see if you have running it in the Task Manager). Others tools that do this are Ranorex and screen readers.

If you don't notice the performance impact, there's no need to worry.
