[orca-list] Libreoffice Calc gets slower and slower with Orca running

[Nick Wood <nick microlitesoftware co uk>]

Hi all,

I have noticed that after a while of editing a spreadsheet in 
Libreoffice Calc, my system gets progressively more unresponsive, to the 
point where Calc is unusable.
If I close Calc and re-open it again, speed returns to normal for 
another 10-15 minutes or so.

I can't find anything on the web about other non-Orca users experiencing 
this problem, so could it be something to do with Orca?

I've seen this behaviour under Orca v3.16, 3.18 and now 3.20, with 
Libreoffice 5.0 and now 5.1.

Does anyone else use Calc regularly and have they seen this issue before?

Thanks,

Nick
