Opening Query tool exausting windows memory - v 1.10.0

Just for recording and help someone if this occurs

PgAdmin 3 v 1.10.0
Windows XP pro Sp3

I was unable to open Query tool window in pgAdmin 1.10.0 , each time I 
try to open, cpu usage go to 100 % and
memory usage jump from around 400 MB to more than 1.5 GB in seconds.

The solution I found : Open Query Tool window in pgAdmin 1.8.4 then 
restore default settings via menu View -> Default View
Then Query tool windows now open normaly in pgAdmin 1.10.0

Best Regards,
