Gravitational micro-lensing can be used to obtain information 1) on the inner structure of active galactic nuclei and 2) on the distribution of compact masses in the range 10−4 … 102 solar masses. A regular monitoring of the most promising candidates for micro-lensing should be carried out. The strongest candidate is the macro-lensed quasar 2237+030, for which we expect a change in the luminosity ratio between the images of about 5 per cent per year.
