Problem select in 3D

[Anonymous]

Hi all. Sorry for my English. We have: two computers ("first" and "second"), XP Prof + SP2, Archicad 9 R1, Video ATI Radeon 9200. Problem: when i open anyone project on the "second" and go to 3D window, i cannot select any object. In 2D all ok. When i in 2D look in propertice or cut/paste object, they begin selecting in 3D. When i make new objects - they selected in 3D without problems. BUT ... Computer "first" ... If i open project on "first", which select rigth in "second", and add new object Now that objects dont select in 3D on "second". But on the "first" all working !!! And if i open projects after "first" on the another computer (not "second") - its ok !!!What i did on "second": change version of XP, change video card, drivers, mods etc. Nothing works. On the logic i understand, that the problem is in the "second". This promlem appear when i change configuration on "second" (old is olny HDD and video). But the computer became more faster. Please help. Is it ghost ????
