Posted: Tue Sep 16, 2008 4:55 pm

In the past there have been several reports of a rare problem that causes the text lines to start getting truncated after a while. Clicking on the screen usually temporarily fixes the problem, but then when more text is received the problem will re-occur.

One of the users who had this problem was able to find a way to reproduce it and send me his test file that showed the problem. We determined that the problem is only caused by certain ANSI color codes, and only when the Scrollback Amount is set to a very large number.

In fact, it looks like a scrollback amount larger than 65,536 is likely to cause this problem, which means it's probably a memory overwrite bug somewhere in the CMUD screen display section.

I've added this to the bug list to fix in the future, but for now if you encounter this problem, just set your scrollback amount less than 65,536 and that should prevent it from happening.
