Custom UIView not receiving touch events for fast mouse clicks in simulator

Question

I'm having a problem in the simulator where if I click fast in a UIView inside a table cell that is setup to receive touch events, it doesn't receive them. But if I click slow (holding down the button for a little bit) the view gets the touch events. I can't test it on the device. Is this a known problem in the simulator?
Thanks.

Hi George,
Thanks a lot for your quick response and jumping to help.
I am so frustrated that I did not get touch event for the custom cell.
I also tried your solution for a custom UIImageView, I put the codes of PhotoView.h, PhotoView.m and TestTouchAppDelegate.m here: Please help to look into it for me.

UIImage *myImage= [UIImage imageNamed: @"scene1.jpg"];
CGRect frame = CGRectMake (0, 20, 300, 400);
PhotoView *myImageView1 = [[UIImageView alloc ] initWithFrame:frame];
myImageView1.userInteractionEnabled = YES;
myImageView1.image = myImage;

[window makeKeyAndVisible];

[super dealloc];
