^me too, i was using 9.27 till yesterday.
, installed 9.52 as "separate install"
but in 9.27, gmail's "standard mode" doesnt work
this 9.52 also has problem in the "text editor" box (of forum's (quick..reply box), mail box....).
when you highlight a word in "text editor", click on it & drag it to other position, it gets
copied
, it should work like "cut-paste" (in 9.27, that's is how it worked).
