How to Adjust sub-Category column width

Right now, on my categories index pages the column width for the sub-categories adjusts based on how many sub-categories there are. I want to set them all to a fixed 25%. As you can see in the links below, when I have four sub-categories, they go where I want them to, but when I have less than four sub-categories, the width increases to equal 100%, thus pushing them down below the image. BTW, this only happens in Firefox, not IE6.

Okay, now I feel dumb, it was right in front of me. Sometimes you stare at the screen so long, you just can't comprehend what you're reading. For anyone who wants to know how I did it, the file to edit is: includes/modules/category_row.php.

I changed the following:
$col_width = floor(100/$num_categories);
} else {
$col_width = floor(100/MAX_DISPLAY_CATEGORIES_PER_ROW)

to:
$col_width = floor(25);
} else {
$col_width = floor(25)

I came, I looked, and I saw everybody lined vertically so nice and pretty in both FF and IE7. Looks good.

I hate to tell you this, but you also have a problem when it is viewed in Opera 9x -- the sub-category images are all on top of each other in the upper right.

I think the divs containing the sub-category images need a "clear: right;" added to them, at least that worked here and doesn't break anything in FF or IE as far as I could tell.

Thank you guys for checking out my site for me! Becky you just saved me so much time and headache as it would have taken me a long time to figure out how to fix the problem in Opera. Thanks a million...
