LTIMUCIN Wow, what excellent technical support I received for USBVision. I was suddenly having trouble running the software after successfully using it for years on a satellite project. After probably 20 emails back and forth, EchoFX support deduced that another software package was interfering (USB Proscope). I relocated a few tools as instructed and BAM everything was fixed. I can't believe the tenacity of this software team to find such an obscure glitch... wish all my packages were so well supported.
