yes, it's been fixed in cs6. you can assign the stage to be as large as 8192x8192.
Downloaded Flash Pro Cs6 and can change stage size but unfortunately now the swfs do not play at all
Has any one else had this problem?
try publishing for the same flash player version you were publishing for previously.
Originally were using FP11.2 and then tried FP11.1 and went back to FP11.2 but couldn't load the swf at full stage with either. We can load a 1920 by 2160 stage but it doesn't look to be the right size - but were able to load the swf with the smaller stage size.(That is a separate issue though - the non-exactness of the stage dimensions.)
We are attempting to output to a two by four monitor array aiming for a 3840 (1920 x 2) by 4320 (1080 x 4) and the large stage size should be possible according to the specs but no go.
