Thunderbird hangs

Thunderbird hangs, CPU to 25% on process. Tried running in (Windows) safe mode, Thunderbird safe mode, uninstalling and reinstalling etc. If I start TB and leave it, I can click on emails OK, but if I try to scroll (or try any other operation), it locks/hangs instantly. AV is Norton, but have tried disabling that and no difference. Tried TB 45 and TB 47b - no difference. Is there a way to just import the emails, without copying the complete profile, so I can try re-creating the profile from scratch? Anything I have missed, or other suggestions (gratefully accepted!)? Thanks in advance. System is a Lenovo with a QC CPU, 4GB RAM running Win 7 x64 Pro.
