Libre Office - Instability

[newtusmaximus]

  LO is at the default setting - whatever they are. . It so happens, coincidence or not?, that Thunderbird is reporting it is crashing. This is periodic. I run updates every couple of days.
The desktop has 3GB Ram, and there is 25gb free on the HDD. The PC is cool and relatively dust free inside -. Can't see any loose connections etc. so presume hardware is OK. The whole set-up monitor / pc / router - LAN etc. all surge/spike voltage protected. No mobile phones nearby - cordless digital phone is nearby but that has been the case for years. No new hardware added/attached.
I reported elsewhere a problem that occurred a few days ( weeks?) after the upgrade to 2.6 from 2.4 i.e. lost desktop background & icons but task bar along bottom visible/functional - otherwise all at that time appeared to be functioning OK.

Not sure whether these recent foibles are an indication of " problem creep" / escalation.
Weird, and staring to get annoying. The reason for switching to LL was that it was rock solid - basic and good enough for SOHO .
I am loathe to back up and reload LL 2.6 afresh just in case a freak mix of additional add-ons via synaptic and other PPAs has just triggered an incompatibility.
Just a thought - a few days ago I downloaded a script  ( arrow.scm ?) from the GIMP forum which enables arrows to be created on pictures etc. - used for  reports etc.    However  I removed GIMP at the same time as LO and restored GIMP 2.8 again, but this time without adding the script.  The script is still  in the download fold presumably "inactive"
I have ( updated) Clamav/clamtk the pc Home folder last night and only one possible threat was identified. This was a encrypted pdf  received by email which was from a known source/scanner . The email was downloaded via webmail. /


Over to you guruss
