Where are my compiler messages?

[GigaGerard]

Sorry that I am new,
Have the red block left to indicate mistake but not the compiler messages that tell me what's exactly wrong with that line.
There must be some window to open to get those, but how?
Note that the "Full command line" option Under menu "Settings" -> "Compiler" -> Global compiler settings -> "Other Setting" tab is ON!
