The blender interface does not response when I click the buttons or key in the text. It change only when I move the mouse cursor away from the button and the text bar.
My laptop is with Intel core 2 duo CPU T5750 @ 2.00GHz 4GB OF RAM. Is this enough for blender.
as far as i’m aware, no. Intels support for applications is, quite frankly terrible. The blender foundation spoke to an intel rep. at the SIGGRAPH 2009 event and had to ask for better Intel support for 2.5, as far as i’m aware 2.5 does perform alot better on Intel cards, but the Intel cards still lack the supporting features, either in hardware and/ or software to work with blender, which is unfortunate, but there is nothing that can be done atm.
I’d try playing around with your intel settings, try turning off AA, if it’s enabled, if the problems persist try running blender with the hardware acceleration turned off, it’ll be slow, but it may be better than what the Intel chip can do.
