I have a simple macro that moves and resizes the front window of the front application in response to a hot key. It works great for every application EXCEPT slack. Trying to run this macro in slack does not work at all.
Some apps do not have normal front windows that can be manipulated with KM. For instance apps that reside solely in the menu bar. Another example is a microphone monitor that i have on my computer (called Mic Drop)…it has a GUI interface that is visible on the screen, and can be moved and resized manually using the mouse, but it is not a real window that can be manipulated with KM. I cannot imagine this being the case with Slack, but since I don’t have it I am not familiar with its interface.
Try this however, in the drop down option where it says “The front application”, see if Slack is listed there, and if so, select it. Then run the macro and see if it moves the slack window or not. That will tell you if KM can control Slack’s windows.
Slack is indeed listed, but I can't control the slack window which I change "front application" to "Slack". I've tried a bunch of other applications (Word, Illustrator, Todoist) and all work except for slack.
