Question: Do buttons and keyboard commands go into #com break when the tags these commands want to write to are offline? 

It was decided when developing Citect for Windows version 3.00 that buttons and keyboard commands will not go into #COM break. This was decided as buttons and keyboard commands can do very complex operations and we felt that Citect could not decide when to disable the command. For example a command may be as follows:

TAG = 1; PageDisplay("SomePage");

If the TAG above was in com break and this button was used to get off this page and Citect put this command into #COM break then the operator would not be able to get off the page.
