I''ve installed on my computer Windows XP Professional with DirectX 8.1 SDK installed. My video card''s a TNT2 M64 with 32Mb of memory using last NVidia Detonator 21.xx video drivers. When I try any example of Power Render 4 TRIAL VERSION (PR4 demo for example) and I press any key to move me, my position is changed to a corner of the room where demo starts. Box animations are accelerated and keyboard and mouse don''t work correctly. On Windows 98 SE and Windows 2000 Professional I don''t have this problem, why? Who can help me? Thanks.
