Tested in v7.83 & v7.83 betas,
On Windows 7 with a 1920x1080 screen size.
When a custom window has a listbox the horizontal scroller will not resize correctly for very long lines.
This affects custom windows where the whole window is a listbox and windows where only a portion is a listbox.
alias show_scroll_error {
window -al @scroll
aline @scroll $regsubex($str(a,800),/./g,\n $chr(32))
window -b @scroll
echo -s l: $line(@scroll,1)
}
Scroll to the right and you will see (on my system) the number 431 instead of 800
The echo confirms that the line does extend to 800.
