Back in Win2000 days, there was a hang problem related to a certain call on the default IME Window:SetActiveWindow on Default IME Window Creates an Endless Loop
. That problem was apparently resolved with a service pack, but it may serve to give a clue (especially in the "cause" section) to the sort of things that might happen if a program somehow incorrectly interfaces with or corrupts the default IME window that's been set in Windows.
A little Googling (for 'default ime') shows that a few programs and games have been involved with issues of IME-related system hangs, up to and including Windows 7, in recent years. At least one 2010 thread involves WMP (Windows 7 - Windows Media Player failures unpredictable
) and, while that thread seems to end abruptly, it appears to possibly have involved Roxio software.
Some information about normal IME messages can be found here: IME Messages (Windows)
and here: IME-Related Windows Messages
, but I'm not sure they'll be of much use with respect to the message you're seeing.--
