Hello, I wanted to add the GUICtrlOnHover to my program that already has ExtMsgBox but it seems they are not compatible with each other. I made a sample that you can test with both regular MsgBox and ExtMsgBox. When running with MsgBox, the script works fine but if you use ExtMsgBox, it will freeze. Also if you use ExtMsgBox and if you double click on the top left side icon to close it, it will close just fine! Anybody knows how to make these two work together? status-hover-test.zip
