well, a little in between holiday release to fix the reported issues...
clrmamepro 4.0b
fixed: rebuilder ignored 'recompress'
fixed: compress to rar/7z created zip files
fixed: little typo in systems dialog
fixed: stats are not kept correctly over sessions (empty stats window)
fixed: biossets with set romof are not handled as biossets (sys1 with soundboard)
misc: don't write utf8 BOM for old-style dats
for the ctreectrl/utf8/easter europe issue, see the other post on my board...
