> What EXACTLY are you trying to accomplish by detecting the WinLogin screen?


I have written a standard Windows application - nothing exceptional.

However, it seems to cause a problem that makes it difficult for very 
few WinXP users to log on again after the screen-saver had been 
activated, and a logon is required.

I therefore want to detect when the WinXP Logon Screen becomes visible, 
and suspend the process that causes the problem until the user has 
logged himself into Windows again.


The problem itself is very strange: Although my software does not make 
use of any functions that might move the mouse cursor, some part of my 
software seems to reset the mouse cursor to one and the same position 
about every second - but only as long as the Logon Screen is visible!!!

That's really annoying, because some users have notebooks with 
touchpads, and therefore need more than a second to target and activate 
the password field! The result is, that they try to hit this field for 
minutes, until they finally succeed by pure fortune!

Really, I'm at a loss trying to find this bug: There's not even a single 
line of code in the whole program that interferes with the mouse's 
movements... :-(
