Probing Holes QTdragon_HD basic

Its been ages since I fired up my mill so I may be a bit out of date with versions.
i wanted to find the centre of a 13mm hole.
I set the diameter hint to 13mm but it was erroring just before the second probe.
I eventually worked out I had  the XY setting set to 10mm so changed it to 13.
I then got the hole centre located. 
I wondered if ths limit should be considered when looking for a hole? Surely the diameter hint is all thats required?
It cost me a fair bit of time so others could easilly be confused.

Maybe its been fixed.

PS. The conversational facing worked pretty well too!

Looking at the latest code diameter hint should be the right thing.
Can you give the error message?

Chris, it said something about probe not triggered innallowed distance.
It will be a while before I can do a test as i have amrather complex job to get out before I can loose my settings.
