I have a header node in which four child nodes reside.
None have borders, padding nor margins.
All four of them have the width:25%; css rule.
In Opera it works just fine, in IE the last block flips to the next line sometimes depending on the width of the window.

I can solve it by giving one block a width of 24.8%, but Opera interprets that as 24% and thus leaves a wide open gap of 1% at the end of the blocks.

How can I solve this? It would be ok for the last block to miss a pixel on the right.
