Recently, I've run into some strange behavior when I use formats with multiple books. It seems that formats applied to subsequent books do not have any effect. Here's a simple case showing the behavior: 
use strict;
use Spreadsheet::WriteExcel;
{
    my $workbook = Spreadsheet::WriteExcel->new("one.xls");
    my $north = $workbook->addworksheet("one");
    my $format = $workbook->addformat();
    $format->set_bold();
    $north->write(0, 0, "One -- this should be bold", $format);
}
{
    my $workbook = Spreadsheet::WriteExcel->new("two.xls");
    my $north = $workbook->addworksheet("two");
    my $format = $workbook->addformat();
    $format->set_bold();
    $north->write(0, 0, "Two -- this too should be bold", $format);
}

In this example, each spreadsheet lives in its own scope, so they should not interact. What happens in this example on my machine that the format (in this case, bold) does not have any effect on the second sheet. This is true for more complicated formats, applied to more cells, etc, but this is a minimal case showing the behavior.

Anyone have any suggestions? Am I missing something here? Thanks!
