Thunderbird crash while opening attachment

Hello,
I’m using Comodo Internet Security Version 3.13.126709.581 (german Version) on Windows XP Prof. Sp3
and Thunderbird 3.0.
Unfortunally Thunderbird crashes when I want to open an attachment e.g. *.pdf-file, *.doc-file or image and then the screen “Sorry, Thunderbird crashes…” comes up. Without CIS running Thunderbird works as usual. Today the crash comes up after clicking on a link in an email.
Has anybody the same problems? What do I have to do?
Thanks in advance.

Hi,

Do you have any version of CSE installed?

IF you have issue with just CIS - please report it to CIS Bug Report Forum (https://forums.comodo.com/bug-report-cis-b132.0/)

Thanks for reporting your issue.

Regards, Eugene.
