Adding modComment to SalesOrder messes up HTML

[Guido1982]

I used the helperScript to add modComments to SalesOrders. Worked, but the HTML is all messed up. The sidebar get launched to the far left bottom and there is a lot of offset on the left. Some problem in a Smarty template?

I used the class method 'removeWidgetFrom' in stead of 'addWidgetTo' to remove the comments and all is well now. Maybe this is some inventory-modules Smarty template issue? One note, this install is not very recent.
