Any better?

Thanks - will check it soon, here is the screenshoot that didn't load up m

Can you check your graphics drivers are up to date and retest.

Also, when you say Safe mode - are you refering to Thunderbird Safe mode or Windows Safe mode?

@Toad-Hall Safe Mode I meant Thunderbird safe mode The graphics drivers should be up-to-date as it was a fresh install of Win 7, with hours and hours of automatic updates. But I will recheck - unfortunatelly I won't be back in the office before Monday. Thanks for replying!
