@zz_tops:
Not sure if this applies but I've seen the gui in firefox not display all the columns if the font size is changed.
When you increase the font size in firefox (don't know explorer) the column headers start to disappear.
Try reducing your font size?
If this doesn't apply sorry
I use both mozilla and IE. It seems the problem continues:S i have reboot the system and also nothing! probaly the webinterface reads the file logs and print it in the Http format. i dont why this cant be done now:S
