When the status bar is fully showing, in the Accounts section (where it shows
the server and the length of time till it checks for mail) if you have enough
accounts that you need a scrollbar, there is a 1 pixel wide area that picks up
the background when you start InScribe. The 1 pixel is between the Time column
and the scrollbar.
If you close the status bar with the - button and the open it again with the +
button it will redraw itself to white.
If you minimize Scribe and then maximize it again, it will pick up the
background again. Resizing the Scribe window seems to have no effect.
See the attachment for an illustration of the problem.
