Windows-8 crash

1
Recently i have  used windows-8
but i noted that matlab(2013b) crashed ,
for example if i use SimpleMovieDemo it
gives a sync error.
but if i use Screen('Preference', 'SkipSyncTests', 1);

matlab crashes.

i remember that i did not have this problem on windows7

is this a common problem?
is there a solution to the above stated problem?

Wow, those instructions sound painful, good luck with that.
Maybe you shouldn't interrupt the script then but add some abort key for which you check to cleanly stop execution if you need.
What i would like to see is the output at Screen('Preference','Verbosity', 6); - Without any of these hacks applied to disable the dwm. Your previous log output hints that the Win32 function ChangeResolutionEx() failed for some reason, although Microsoft docu doesn't indicate any new incompatibilities with Windows-8. Would be good to know what the error condition was and if anything can be made a bit more robust against it.
Was the system running on the internal flat panel only?
