Thanks for the clarification. My OP correctly referred to a .wsf file but my aging brain subsequently converted it to .swf
Since my last post I had already discovered that a .bat file was an alternative to a .wsf, though batch files have the disadvantage of causing a short flash on the screen. However, I've never used Curl before, so thanks for that info.
I still have an issue with the MCC 10037 command, as it appears to be behaving in a rather erratic manner.
Using the command prompt, I can turn detached display on for the current zone with
MC32 /MCC 10037,1 and turn it off with
MC32 /MCC 10037,0. So far, so good, but when I specify the ZoneID the situation becomes more complicated.
MC32 /MCC 10037,1:0 correctly detaches the display for Zone 0, but
MC32 /MCC 10037,1:10038 also detaches the display for Zone 0 (but not Zone 10038). The same applies when I use other ZoneIDs in the command. They all detach the display for Zone 0. What might explain such behaviour?
