[Gimp-user] GIMP 2.8.0 WIN32 - Very Slow

[Andrew Clarke <andrew_bridget btinternet com>]

Just installed GIMP 2.8.0 win32, it seems very slow when editing images, 
for example if I use the spray brush the cursor moves but the tool 
'circle' does not move or lags behind. The change in the image also lags 
behind the cursor.
My system: Dell Vostro 1520, Intel 2 Duo CPU p8700 2.53GHz 4gb 32bit 
(Vista).
Had been using 2.7.(not sure if it was .4) no problems. I have increased 
title cache to 3gb but no change ?
