I'm working on an XP gina that, among other things, sets a timer to wake up and do some administrative tasks at a certain time. Occasionally the WM_TIMER message appears not to be delivered to my gina. Not just late, which the gina can expect and tolerate, but never.
MS KB article Q322913 "WM_TIMER Messages May Stop Being Delivered to Programs in Windows 2000" describes this problem for Windows 2000 and indicates an available patch that replaces winlogon.exe, msgina.dll, userenv.dll, and several core OS files.
Does anyone know if there is an XP patch available for this problem? How/where can I locate this patch, if it exists?
