Gnumeric and Abiword sluggish after upgrade

[Stephen Barratt]

Hi all,
Just upgraded to ubuntu gnome 14.10 from 14.04. It appears Gnumeric is 
struggling to operate smoothly now (it was fine before the upgrade). Has 
anyone else noticed this?

I checked abiword and the same problems are apparent. Menus are slow to 
appear and the entry highlight very slowly follows the cursor. Opening 
'top', I see 'gnome-shell' soar to 100% cpu usage as I whiz the cursor 
up and down the 'File' menu (and the others) of gnumeric. Repeating this 
with other programs (eg Calc) it maxes out at 20-30% even with my most 
fervent mouse whizzing.

I've tried reinstalling gnumeric, changing shell and gtk themes to no 
avail. I tried building(?) the latest version by downloading, extracting 
then going through ./configure make etc but it stalls installation 
suggesting a gtk3.0 version dependency was not met however this may not 
be related I assume.

Any ideas?

Cheers,
Steve
