Problem with a code that fades modules Options

[computershateme]

I'm using this code to fade the left modules:
<!-- begin code provided by createblog.com -->
<style type="text/css">
table.left {
filter: alpha(style=0,opacity=60);}
</style>
<!-- end code provided by createblog.com -->
It works to some extent, the modules fade...and it's fine for about 10 seconds, until you hover over them. Then, for some odd reason, the profile module's bottom border dissapears along with the right borders of the subscriptions, blogrings, and posting calendar modules. It's weird, in the last three if I hover over a link in one of them, the border comes back, but then dissapears as soon as I hover on a link in another module. Does anyone have any idea why it does that? If it can be fixed? Or is there another code I can use that fades all the modules without that weird reaction?
