[amibroker] Re: Image CopyProblem even when copied to
Word.Friends,Similar problem comes-up if the
copiedimage is pasted into MicrosoftWORD. So I guess there is a
bug inAmiBroker. Are there any otherswho have noticed that there
is a bar atthe bottom of the copiedimage copied using 'Edit->Image
Copy' ?Regards,- Salil V Gangal--- In
