Thanks for the feedback.
Yes, the laptop is running 32 bit Vista Business. Using the X button to close it works fine. And the macro list displays correctly when I reduce the total number of macros to ~20.
My setup is relatively stable right now and I’m primarily using the EZSrve web interface for minor modifications. I mainly use the SHN Utilities control window to monitor X10 and Insteon traffic, but I occasionally use it to look at and change links. I’ll try to use the Vista laptop the next time I need to change a link and let you know if I have any problems. Is there any other functionality it would be helpful for me to test?
