first, let me say that TP is really a great program. Thanks for it.I don't know what I did, but every time tp is started, it starts giving messages :tileproxy.sys: pre create: changing rilename on the fly to progfiles, (followed by the address of the particular bgl file),ending with (ptx(number).bgl.on). It renames all the files and stops. As soon as flight simulator is started it does it again.The only thing thatI remember doing is to change services.I uninstalled tp, deleted everything I could find that looked like it belonged to tp, reinstalled tp and it still does it. Any suggestions about what to try next?TP beta 5 by the way.Thanks, Bob

sorry, I dont know where the ugly face came from either.it was supposed to be an open parenthesis.bob

This .bgl.on thing is a normal new feature of Tileproxy Beta 5. Don't worry.Does the program still work?

Thanks for the reply Cristian. tileproxy.sys gives lots of messages which say it cant find the file allocation information, but it seems to load ok and also run fine.I downloaded a new version of diskeeper, my disk defragger which has a new feature to arrange files in the most eficient way for speedier reading. I have turned off that feature to see if that was the cause of all this.thanks again Bob
