ShowWindow, SW_MINIMIZE, Cascadia window - only works sometimes?

[vefatica]

If I ShowWindow(g.hWndCascadia, SW_MINIMIZE); it only works about half the time. The rest of the time it minimizes only momentarily and it is immediately restored.

SW_SHOWMINIMIZED and SW_SHOWMINNOACTIVE work every time but don't activate the next window in the Z-order.

... any idea what's happening (and how to work around it)?

Thanks.

Never mind. It was my fault. I was messing around in a WinEventHook (for EVENT_SYSTEM_FOREGROUND) simulating a mouse click to get rid of the busy mouse pointer (which I was seeing way too often). I got rid of the hook and SW_MINIMIZE works as expected. If the busy pointer bugs me again, I'll reinstate the hook and do some work on its hook process.
