I've got a couple of shortcuts on my desktop and on some of them I've configured the "Shortcut key" to a keyboard combination. For example I have a shortcut pointing to d:\documents\todo.txt and I've set Shift + Alt + T. This naturally opens up using notepad.
Double clicking on the icon always opens up the text file immediately. Using the keyboard shortcut though is sometimes very (5-10 seconds) slow. Note that during that time CPU utilization does not rise.
This happens to all my machines (both old and new ultra fast boxes) in Windows XP (various versions) and Windows 7.
There are tons of questions about this but no solution.
Is there an explanation and solution to this problem?
Edit: The behavior is not consistent. I have 30 desktop shortcut and 5 of them have keyboard shortcuts assigned. I'm not interested in software alternatives for this windows functionality. I want to know what the problem is and how to solve it.
