I have a GUI application running on Tk. Up until today it worked nicely on Strawberry 5.32.

After upgrading to Strawberry 5.40 and applying the Tk patch Tk-804.036_001, the widget demo works as expected but my application does not.

The thing that no longer works is that floating point numbers are suddenly represented with comma instead of period, which seems to be a side effect of calling Tk::MainWindow->new().

As a consequence of this, all my floating point (and there's a lot) are now treated as integers, making e.g. 1/0.1 yield div by zero.

use Tk;
$x = 1.2;
$sq = $x * $x;
print "Before Tk call $x, $sq\n";

$Window = MainWindow->new();

print "After Tk call $x, $sq\n";

yields(notice the change in comma separator)...

Before Tk call 1.2, 1.44
After Tk call 1,2, 1,44

[download]

When using the debugger and entering a simple "x 1.2", a single 1 is returned. x 1/0.1 yields division by zero

Any suggestions on what ty try next grately appreciated. I would hate to have to go back to 5.32.
