Coherence: My favorite new feature... but when im doing dev it's becoming almost unusable. So, when using in windowed mode, my 2nd favorite new feature is the auto adjusting resolution with the window resizing. I'm still trying to figure out what happened... but when my XP began to bog down I checked out the running processes, and there was three instances of dumpreq.exe running each using 33% CPU. I checked... these are nothing that I started, or related to any program that I use. I can only imagine that maybe this is one of the helper processes that Parallels Tools uses? When I killed each one, the remaining took up the rest of the CPU (2 split at 50/50 and when there was 1 it was 100%.) I had switched in/out of coherence mode a few times during that instance of my XP VM. Also, while using coherence: I use a modified application switcher to replace alt-tab in windows: TaskSwitch XP (I don't know if this problem is only related to that application, or any alt-tab use at all.) But while the application switcher is up, the background is painted. Then when it disappears you get parts of it left that are sort of artifacts that always stay painted. There are various other tasks that make the background re-appear (ctrl + alt + del while running in a domain mode [i.e. when the user screen is painted as the background and you get a window giving you options, one of which is the task mgr.]) Whenever it is re-painted, there are problems from then on with the painting of the background (which shouldnt be painted at all, obviously.) Love the concept of coherence, and if the bugs can get worked out it would be fantastic. From my usage already, my main comments and suggestions for improvement would be: Find a way to make running applications in windows appear in the OS X application switcher (cmd-tab.) When selecting one of these, it could simply bring parallels to the front, and in the VM move that windows application to the front. Doing this would greatly reduce the need to have the task bar appear at all (which would be awesome.) And, if this became the case, there should a way to set a hot ket in Parallels Tools to draw the Start menu, or some way of launching applications (think QuickSilver for windows? That might be asking a lot, but it would be nice.) That would be my ideal setup: Having no start bar drawn, with no windows background, and being able to use the same application switcher as OS X to select applications.
