You are doing something wrong. How exactly do you retreive the message? Note that for gadtools, you need to use GT_GetIMsg(), not GetMsg(). Also, do you check the return code for GetMsg() for NULL?...

There is nothing to click on, so why should it register something? IDCMP events are created whenever a gadget changes state, but there is nothing to change here.

In general, I believe it is a bad idea to patronize the user. Thus, if the user decides to click somewhere else, for whatever reason, then the program should rather tolerate that.
