I can verify the same issue. If any application including altbinz pops up a balloon tip within the systray, it will cause Altbinz to lockup. Also, when it starts verifying and repairing, it will also lockup.
Issue is identical on another system as well. I have tried all available versions of Altbinz for an alleviation and all versions freeze when repairing files and/or a balloon tip pops up.
The only way to shut it down is by killing the process (WHICH i notice, seems to hang at 25% CPU everytime it has frozen). If left long enough, the comp(s) will reboot due to CPU overheat protection
Running latest Altbinz on
