Thank PHeMoX and jcl.

I where can find out acklog.txt, C:\the program files\gstudio 6 can't find out this file.

my desktop is 1024 x 768.

My usage template and display 00. wdl set: video_mode = 8; video_depth = 32; version 6.4 and 6.50.2 is good, 6.50.4 And 6.50.6 regardless video_mode=8 ors 9, all of the max screens are 800 x 600.

However the press F5 can change to the 1024 xes 768

How should I do? Thanks.
