Change the style in the more popup window

Check the function named ProcessLargeText(strValue, iquery, table, mode) in include/commonfunctions.asp file.

If you like to modify More ... popup appearance this is the right place to do this.

Thanks Sergey,
Is there a simple way to change the style in the same as the basic style?
And, another question, i'd like to hide a field in the list page, the only problem is that this field the key is of my database?
Is this possible?

Modify this function to make popup window use the same stylesheet file (include/style.css).
Yes, you can hide the key column.
