Projects stop showing content after clicking through index a few times.

My website is www.saipromsri.com
I am using Mondrian template (modified to horizontal scroll). I added tr {vertical-align:top;} to my CSS as below:

tr {vertical-align:top;}

body, html {
margin: 0px;
padding: 0px;
}


and rearranged my Contents and Layouts of all projects to a format below:

<table><tr><td>{image 1}
Newsletter and invitations<div style="color:#999999;"">Designed with the Velocity Creative team</div>
</td><td>{image 2}
</td><td>{image 3}
</td><td>{image 4}
</td><td>{image 5}
</td><td>{image 6}
</td><td>{image 7}

When clicking through projects on the the left hand side menu, the contents stop showing after clicking though 2-3 projects.

What can I do to fix this issue?
Thank you very much,
