It is a little bit surprising to find out that IF:M breaks the mouse click/release event

Try this code:

What you want to do is to click on the first town of the list (item 32). You get a IF:M msg show correct item ID. And then try to click on anywhere of the Adventure map, you will again get the msg saying mouse item is 32, which is wrong (should be 37).

This is because in the mouse event was interupted by the frist IF:M and the "mouse release" part of the event was only triggered when we click the second time. It is understandable, but kinda surprising.
