There is a simple fix. Add the following line to the file showflat.inc.php
$file_descp = "";
Add it right before the following code.
if ($file_desc) {
$file_descp = "<p>" . $file_desc . "</p>";
}
I sent your fix to our IT guy and he says that it will be erased whenever the software updates. It would be really nice if a more permanent fix was implemented, as the caption carryover is STILL occurring.
