I'm using an alternative IME on Windows, which can be found here:
I personally use the Greek Tool, being a Greek and all...
This IME helps speed up the typing enormously for a foreign language.
Unfortunately, whenever I switch keyboard layout to this IME, Notepad++ always crashes from the first character I try to type.
Windows XP SP3,
Windows 7 SP1 x64,
Windows 7 SP1 x86.
Attached is the dump file from the crash.
