I do it manually yet it didn't resolve my problem.
My resolution is 1024x600 (Netbook Aspire Acer One D270 - 2gb ram)
Since it was a mini laptop used for browsing, light games and internet only, i guess this was the problem. any dev can help me? it is much appreciated.

Too bad... Native resolution too low.. Can't use as bot is using pixel search with 720x860 Resolution.
Try plugging to spare monitor (external) if possible and see if it work.

Can i use my 32 inch lcd tv? i'm really desperate this time. seriously

Why not.. Try and tell us..

still not working i should switch to my desktop then.

try using a 16:9 monitor.
and change the resolution, minimal height 768 (720 for BS, 48 for the taskbar or something).

nb: bigger monitor may causing lag or hang, depend on your VGA, RAM and Processor CMIIW
