I believe the correct setting is called TTDT_INITIAL
, as outlined here: TTM_SETDELAYTIME (Windows Embedded Compact 7)
But in searching for it in my registry, I find nothing. And in searching TTDT_INITIAL
I only find people discussing coding for applications, not registry hacks for Windows.
I does seem Layback Bear's suggestion in post#3 in this thread should be the correct setting
This will show you how to change the delay time, in milliseconds, that the mouse pointer has to stay hovered on a item before tooltip popups display in Windows 7.
