the defendant complains in his post-trial motion that the composition of the venire deprived him of a fair trial. During his argument on his post-trial motion, the defense counsel again claimed that there were only four minority members on the 44-person venire. The judge stated that five members of the venire had appeared to him to be minority members and denied the post-trial motion. We agree with the State that the defendant has waived review of this issue by failing to challenge the venire by a written motion supported by affidavit. See 725 ILCS 5/114 — 3 (West 1992); People v. Johnson (1987), 154 Ill. App. 3d 301, 507 N.E.2d 179 (finding waiver when the defendants did not support their written motions with affidavits); People v. Flowers (1985), 132 Ill. App. 3d 939, 478 N.E.2d 524 (<HOLDING>); People v. Perry (1980), 81 Ill. App. 3d 422,
holding that two general objections were insufficient to properly preserve the issue holding that an oral challenge to the venire is insufficient holding that the defendants oral motion challenging the venire was insufficient to preserve the issue for review recognizing that the specific argument regarding an issue must be made in the trial court to preserve that issue for appellate review holding a general ruling by the trial court is insufficient to preserve a specific issue for appellate review
