Try this from xda at your own risk
Here comes the tweak:
I've been facing this issue where the SIP menu (aka input menu), takes like 2 seconds to popup when you want to switch the input method, making me wonder if I didn't manage to press the little triangle... My old PDA didn't have such an issue.
So after some searching, I found this:
give it a shoot , Get a registry editor ,
1. Export HKCR\CLSID (will save to a *.reg file)
2. Del or Rename HKCR\CLSID
3. Import the backup of HKCR\CLSID
Turn off your device about 15 sec and reset
