Strange overflow behavior

Hi. I'm remember worked with Hypersnap (I don't remember what version) on 2007 with the text snap functionality.
I could get some data from an app really fine (on that time I used XP).

Now I'm trying to do the same on Win7 64 and WinXP (running on a Virtual Machine) and doesnt works.
The process that I use is "Text snap region with autoscroll"
 
To clarify:
On WinXP (VM) with version 6: doesnt work more than 2 or 3 clicks. 
On WinXP (VM) with version 7: doesnt work more than 2 or 3 clicks

On Win7 with version 7: doesnt work more than 2 or 3 clicks 
 And this is the best approach I get it:
 
Windows 7 HyperSnap 6:
It does the work but everytime stop at random time and when you get the results, only can be copied the same total of bytes, aprox 66kb. If you begin when you stop, again, only copies 66kb.
 
How can i solve this and/or what's the configuration to do work it?
 
Thanks and kind regards
