Hello Vin,
My apology for my post is coming in from left field, given the current focus on the SMS problem.
I have been using nSnT ROM. I use multiple languages and so often need to switch SIP-IME combinations. In WM 6.1 when I pressed SIP icon it would toggle deploying or removing the SIP from the screen, and next to the SIP icon was the little arrow for changing SIP. In Pluto ROMs repeatedly hitting the SIP icon does not toggle the SIP on and off the screen. When you repeatedly hit the SIP icon it deploys SIP choices. Is that the way Pluto is supposed to work?
Is there a registry edit that will make hitting the SIP icon toggle on-screen & off-screen behavior?
Sincerely,
Andrew
