BSOD with burning softwares

Sorry for bad english.

Thanks for distributing Comodo Firewall as freeware. I use it since few months and I like it.
I would like to report a bug.
I’m using XP home Sp3 and CF v3.5.54375.427 Defense+ disabled.
Since few days, when I started a burning software the system crashed with a blue screen of death Stop: 0x0000007E.
I tried different burning softwares, BurningStudio, StarBurn, DeepBurner or CDBurnerXP, changed drives drivers… the problem was the same. I found a ligne in minidump files with cmdguard.sys so I disabled CF and renamed this driver as .bak. After reboot, everything seems OK!
Do you know this problem?
