Pickfirst is on and objects just don’t select

Today I encountered a strange AutoCAD issue. At first it seemed to be the old pickfirst issue where if the variable is off you have to run the command then select, rather than the default behavior where you select and go.

The issue encountered today was similar but only seemed to happen on CTRL+C and mtext (MTEDIT). Otherwise all commands worked with select then run command.

After a bit of searching this error appears to be an issue with QAFLAGS. QAFLAGS is an undocumented system variable that appears to have no obvious use. It is problem an internal AutoDesk variable for testing. Though its strange behaviors can be used to assist in writing LISP and scripts!

QAFLAGS can be set to 1 or 2 apparently but the default should be 0. If it is not on 0 the strange semi-PICKFIRST=0 behavior will occur!
