Make sure that your glas plates are properly silanized.
I got good results with a soln of trimethyl chlorosilane in pentane 
(e.g. from fluka, less hazardous than the widespread solns in 
1.1.1.trichloroethene). In case of doubt, "oversilanize" it. Maybe 
your silane soln has gone dead? (assume it's a bit sensitive to water
