Error from compose.php

[Jan Kuipers]

Hello,

I get the following error, when replying to a message from _another_ folder, 
then the INBOX folder.

Warning: Bad message number in /somepath/imp/compose.php on line 499

Warning: Bad message number in /somepath/imp/compose.php on line 566

Strange thing is that it only occurs with NN-4.7x, Mozilla 0.9.8 and Opera 6.0x!
IE-5.x or > works fine!

FYI this error occurs the last couple of days in the HEAD branch.
with compose.php v. 2.412 I don't get this error.
