Help Why do I get this?

[Ric WRX]

Whenever I click on Active Applications, I get this:
If you force stop an Application, it may cause errors
Yes No
Does this really cause errors?

In my several years with android, it's never caused any problems for me with force stopping an app when needed to.

It's just a precaution.

It could happen (that's why the warnings there), but its not very likely. Worst case scenario if you'll unrooted you may need to factory reset to clear your caches
