cfimage with captcha does not display all the text

I am using the cfimage tag with action="captcha" and text="someText".  SomeText is replaced with a random string between 4 & 7 characters.  Sometimes when the captcha is displayed it doesn't show all the characters that was passed in the text argument.  For testing I display the text that is passed into the cfimage tage above the captcha box so I know what should be displayed.  I also tried putting in static text like the word test and there were times it didn't display all 4 letters.

I am using Coldfusion 11

Any ideas?

What are the width and height dimensions that you are setting for the image?  There might be a minimum width/height in order to display all the letters.

HTH,

Hmmm.. that _should_ be large enough..

I should have asked this in my first response, but didn't think of it until now:  Could you please post two or three screencaps of when it isn't doing what you think it should do?

V/r,

In this case I am passing in H9JPB and it isn't displaying the "J"

In this case it actually displayed the wrong letter.  It should be AD738 but it dplayed 0D738.  The 0 or o isn't even an option as one of the possible characters

in this case it isn't showing the "N"

That's a head-scratcher, for sure.  I can't think of anything, off the top of my head, that would cause that to happen.  Especially displaying "0" when it should be an "A".
