During high CPU usage, caption bar buttons don't stick to parent window

Sorry to report this, but if the CPU is pegged and and down to even to only 50% utilization, the caption bar buttons begin acting like mouse tails, following the window as you drag it. I've even had an instance where when a window was created with the CPU pegged. The button appeared behind the caption (which is to say, the SW_SHOW on the button was handled before that on the newly created window!).

Unfortunately there isn't much I can do about this. :( When the CPU usage spikes and another application starts hogging it, DisplayFusion takes a backseat. One thing you can do to alleviate this a little bit is to run DisplayFusion with a higher priority. In Task Manager just right-click on the DisplayFusion process and you can adjust the priority level. Also, in Beta 5 I have added an option in the Options tab to run DisplayFusion as a high priority process. :)
