I was testing this out, and I run 98se as well.
The 2 window splits (filename box, and comment box) dont resize with the whole program at maximization.. they just kinda get shifted to the upper left.
I'll provide a screenshot as well.
As a side note.. on your 'known issues' page you can get rid of the question mark after the 98. Because I think after 2 people having the problem, it would be a definate problem with the OS, and not a possible problem..hence the removal of the question mark!
window "parts" don't resize with the main window on Windows ME (95/98?).
