I have a multi colour touchscreen job that I just recently revisited and added some more code and pages to the project. When I went into the load monitor to mark some new c-bus groups to be saved, almost ALL of the groups had dissapeared! I checked the other touchscreen project and the same had happened - although most had dissapeared, different ones had gone from the 1st project. I have tried refreshing the list, but I can only get a very small amount of groups to appear in the list. I had upgraded from v3.3 to 3.4 in the meantime - maybe something to do with it? The project is a big one, with over 100 system IO, 300 C-bus groups and 2,500 lines of code. Any ideas? :confused:
