I am noticing a bug in the buffer display when it scrolls. When I use the Arrow key/Page Up key to scroll back (NOT downwards), the display of text gets garbbled. The contents at the cursor location is mysteriously shifted (copy) to the top of the visible part of the buffer. The lines under the cursor position are copied at the end of lines of the top part of buffer. After a decent interval of time, when the buffer update happens next (on my machine, it was 30secs of idle) or when some other event triggers the buffer update, things are normal. I have a JPG image saved. It is 150Kb size. If some one needs it, I can send it across. In the mean time, I will test it with no user customization. Since this is quite random, I need time. Also, if this problem occurs once, it is repeatable in the buffer. A page up will garble it, a re-display will correct it, again a page up will garble it. with regards, dhruva PS: I might have sounded confusing. I know it is an art to clearly express yourself. As a developer myself, I would find the description I have given rather confusing. Let me know if you need more information or if I can debug it myself further through MSDEV/GDB. --=20 Dhruva Krishnamurthy Home: http://www.geocities.com/gnued/
