Sorry about that.
There are two solutions.
The first, which should work for any browser is to open two windows (one for moola and one for MoolaHelper) at specific sizes.
Click here to launch the two windows
The other, which works in FireFox and Opera is to use the Sidebar.
The sidebar is actually much slicker than two separate windows.
Click here to setup the Sidebar
Allow it to create a bookmark. Clicking the BookMark will launch the page in your FireFox or Opera Sidebar.
