[Lazarus] MDI Child form goes behind MDI main form

[Eduard Filipas]

hi
enviroment: win7 64x, lazarus 32bit version 0.9.31; date: 2011-02-05; 
SVN:29379

problem arises when having form style MDIform and others mdiChild

if you create form on run time forms normaly shows but if you click on 
mainForm then child form goes behind mainForm ..which is annoying anyway 
it is for me as this differs from delphi ..child forms should stay on 
top(infront) of mdiForm..

Best regards
Edo

P.S.
if i should report this to somekind of bug-tracker...please advise howto ...
