Bug 690 reopen?

Hi, I wanned fix bug number 690 and get rid of high cpu usage during kdm login screen. So I first tried daily-build and when I get know, that it's not stable for daily use i downgrade to Slavek's pathed 3.5.13 (http://trinity-users.pearsoncomputing.net/?0::2776). In both case, there shoul be that bug fixed.However, problem seems to be still there (on my coputer) and as a bonus I get another one. When there is "Press ctrl+alt+delete" window there, I can try keep pressing these keys, but windows is still there and I can log in. Any advise? How to debug that? Can I reopen this bug? Regards Jirka
