masonry-responsive columns

hello,
I’m attempting to use jQuery Masonry in a responsive design and it’s not working properly.
Sometimes, the desired number of columns are not displayed:
Example:
Windows-Size: 1024 px
Actually here should appear 3 columns , but there are only 2 displayed.
From 1038px 3 colums are visible..

Any help?
