请问下面程序想实现在左边图片框中鼠标单击任一点蓝色区域实现在右边图片框把与刚才点选的那一点相连续的所有点变成绿色，为什么会出现“实时错误28，堆栈空间溢出”的错误呢？谢谢各位了。代码如下：
version 5.00
begin vb.form form1
caption = "form1 "
clientheight = 6285
clientleft = 60
clienttop = 450
clientwidth = 9000
linktopic = "form1 "
scaleheight = 6285
scalewidth = 9000
startupposition = 3 '窗口缺省
windowstate = 2 'maximized
begin vb.picturebox pic2
autoredraw = -1 'true
autosize = -1 'true
height = 2295
left = 5640
scaleheight = 149
scalemode = 3 'pixel
scalewidth = 173
tabindex = 1
top = 120
width = 2655
end
begin vb.picturebox pic1
autoredraw = -1 'true
autosize = -1 'true
height = 4830
left = 120
picture = "form1.frx ":0000
scaleheight = 318
scalemode = 3 'pixel
scalewidth = 356
tabindex = 0
top = 120
width = 5400
end
end
