I got tired of zillions of COM ports being created when i need to program some FT232 chips. Safe mode and all the other tricks didn't work. I finally re installed XP. and even that hasn't 100% cured it, which seems quite odd. next step is going to be wiping the partition. I can program the devices on the Mac now, so I'm not going to mess with this on the windoze box again, assuming I can even get it back to a stable (relative to windows) operating condition. -- --- Chris Smolinski Black Cat Systems http://www.blackcatsystems.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
