hotspot in games

Got an issue and I assume it's a Windows 10 thing and not specifically a game issue and that is while in any game if you move the cursor to the very top left of the screen it drops the game back to desktop, so far it's happened with both x3 Terran conflict and Eve Online, it seems to be some sort of hotspot if that's the correct term, is there any way to disable these hotspots so that no matter where you put the cursor it won't drop back to the desktop. Thanks in advance for any help.

Try turning off Peek in the Taskbar settings. I'm wondering if you have your taskbar in a different place to the default bottom setting.

did a whole lot of searching last night, seems that my program launcher (FSL Launcher) had the top left corner set as a hotspot, after disabling that all is good thanks for the reply all the same.
