This appears to do with parsing error of the log file. Either with the colored blocks or linebreak.

I attach the log file it was looking at even though by now the tail is different since the job is now completed. Neil, this is your code. Could you take a quick look ? I It works fine with the default (13) but not some other values such as 14 where it encounter a colored block.

This has been a problem since the beginning of Appion. The text is all there if you highlight it, but the font color is black. I tried to fix it several years ago, but could not get it to work. Eventually when the program finishes it will display correctly again. I think Anchi is right when she says it has to do with the color coding.

Neil,

I did some page source research into the problem log. Problems came from the appion display colors where colorString starts with 0;. It may help you in debugging this. In any case, I have a work-around solution: set the background color to grey, instead of black. #808080. If you don't find a permanent fix quickly, could you just change the code to use grey background ?

the 0 (zero) is used to reset the color on the terminal, I guess it sets it to black in the viewer (black is actually a different number like 30 or something). I do not think we can avoid using the terminal color reset. It had been like 7 years since I looked at this, but I recall trying to set a white color when it see the reset.

I do like the gray compromise.

Even though I added more color coding, the html may still decode string like '<<<<<<>>>>>>' into termination of font color. The workaround is the best to do now.
