Nor, did defendant preserve any challenge that court personnel improperly communicated with a juror in defendant's absence. In any event, the exchanges in question were merely ministerial (People v. Roldan, 173 A.D.2d 233, lv denied 78 N.Y.2d 926; People v. Townes, 165 A.D.2d 761, lv denied 77 N.Y.2d 844). Likewise, defendant failed to preserve by specific and timely objection any claim that the court excessively interfered in the cross-examination of one of the People's witnesses (Peoplev Charleston, 56 N.Y.2d 886; People v. Hunt, 167 A.D.2d 272, lv denied 77 N.Y.2d 878) and defendant's motion for a mistrial several days later did not serve to revive the unpreserved claim (People v. De Mauro, 48 N.Y.2d 892, 893; People v. Merriweather, 175 A.D.2d 90, lv denied 78 N.Y.2d 1013).
