the new version 4.1.150349.920 kept hanging and even crashed once, I was also unable to shut the programme down once it hung. After this happening many times I realised it kept hanging at roughly the same spot of the scan (and crashed one time)!
It kept hanging at software from Web CEO 8, for example at a place like this: AppData/local/Web CEO/BIN/icslite.bpl
I removed this software and once it was removed the scan continued without any trouble? I can now also stop the scan and close the scan down. However the software is still removed.
sorry, can’t tell you any more than this, not a computer expert!
