KS10 trouble with old scene (KS8/9)

[Zeltronic]

Just want to test some old scene in ks10 , (ks8 & 9) and have some troubles with this one especially,   this have been done initialy with ks 8, I cannot move parts position interractively in real time view in ks10 on this scene ??!! the workaround is to switch to wire view and then I be able again to move interractively parts but only in wire mode
