Possible Line highlighting bug

[Lux]

I am running Cacti 0.8.4 on Win XP. I have recently noticed that the line highlighting (When creating new graphs) is not working for two of my devices. The problem seems to be linked directly to these specific devices.

I have tried deleting the devices and reentering the device in polling hosts and I have tried entering the same divice in multiple times, but have not had any positive results.

The two devices are a Cisco 3640 (IOS 12.2(3)) and a Nortel PassPort 8600 running OS 3.2.2.4. I am polling several other devices of the same types and the highlighting works fine with them.

Does anyone have an idea
