no response of chart

 
I have tried to set chart offliine 2 times (right click, properites, then set offline)
1. first time, no response, and then mt cannot be invoked again, need to uninstall and install again, my ntfs has bad
links (no sure the abend causes bad link, or vice versa)
2 2nd time, also no response, but can work later (ntfs should be ok at this moment)

can anyone repeat this?
