Under Windows 7, 64 bit, I sometimes get the error "A call to an OS function failed" when Qimage is started. Qimage seems to take longer to start up when that happens and once at the Qimage workspace everything works (although much slower than a year ago).  Other applications like Photoshop (even 32 bit Photoshop) are getting faster, Qimage seems to be getting slower on the new 64 bit platforms with faster processors and memory.
