Unicode files created with 4.5 damaged by 4.7

[mkdna]

Hello,

i created unicode encoded XSL Stylesheets with Textpad 4.5. When i edit such a file with textpad 4.7, the file is no longer opened by internet explorer and can no longer be used by the microsoft xsl parser. Comparing the files, i found out that the first two bytes of the old file are missing in the new file (Values: $FF $FE). Looks like this is some sort of unicode identifier.
What happened ? I switched back to 4.5 and everything works fine again

Any ideas ?
