Extremly slow compile Clarion 11

Hi,
I have strange problem with compile on Clarion 11. Some app after first compile, get slow on every other compile unitl I get out of Clarion 11 and load again.
It took few minutes to compile on second and every other time. First compile take 15 sec.

Any help about it ?

There’s an option somewhere (Options?) about Clarion keeping some info cached. That might need to be toggled
