Thank for the help leather-guy, Philywebrider as leather said the 1.5.4 is a beta release. It will soon turn to a full version but you can download the 1.5.3 to get the necessayr DLLs. Don't hesitate to mail me at yarp@senosoft.com if you have any question. I'm dug into problems with this 1.5.4 beta. I now have an XP testing machine and I found many bugs related to Unicode (the famous lock) and 32 bits (black or transparent thumbnails) that many of you should have met. So I'm fixing those bugs and then 1.5.4 will be far more portable than previous P3dOs were.
