[Lazarus] how to show hourglass on windows 10 with touch screen?

[Luca Olivetti]

This isn't strictly a lazarus issue, but my google fu is failing me.
It turns out that windows 10 with a touch screen hides the mouse cursor, 
so Screen.Cursor=crHourGlass does nothing.
I found that there isn't a setting to force the mouse cursor on 
(https://answers.microsoft.com/en-us/windows/forum/all/show-mouse-cursor-also-when-using-touch-screen/e9a7ab79-baeb-4b47-afee-4d8fed4cfbcb), 
is there an alternative way to show that the application is busy?
In my case I'm launching another application and, since the pc is rather 
slow, it could take 2-3 seconds or more for the application to show 
after pressing the button.

TIA
