I had this issue and apparently a few others are having the same issue. In Internet Explorer the f2.gif arrow at the top of the left blocks column does not align properly at the right of the column.
Here is the fix I am currently using. I haven't determined yet if fixing this issue created another issue. <_<
In /mkportal/functions.php find and comment out the following line...
$mklib->boxwidth = isset($MK_CONFIG['box_width'])?$MK_CONFIG['box_width']:"140";
In /mkportal/templates/default/ find and delete (or comment out) all instances of the width attribute from the blocks functions.
width="140"
That did the trick for me.
