2009/12/8 Les Hardy l...@webmayo.com: This is a Linux thing. Not Gambas. Linux has a lot of things. I learned the hard way that localhost TCP/IP ports below 1024 are protected. Sheesh. I lost a full day to that. Today I lost several hours to Gambas behaviour that is expained by bugs in Qt3. Nevertheless your point is valuable.
