Ironically the GUI of guiminer.exe (2011-07-01) disappeared from my Windows 7 x64 machine.
After investigating, I found out that poclbm.ini's settings for "window_position" were changed to -32000 for both horizontal and vertical positions. I reset them to 0 and I could see the GUI again when launching guiminer.exe. Hope this helps other people. You may want to check why it resets to -32000 instead of 0. It happened a second time to me just now, while I was opening and closing guiminer.exe to test it. Here's the ini content:
"window_position": [
-32000,
-32000,
160,
27
]
Also, I noticed that the poclbm.exe process is now taking up 50% of the CPU usage, with the first of the 2 dual core CPUs at 100%, when it used to be 0% with the 2011-06-09 version of guiminer.exe. I saw that "CPU Affinity" had the #0 CPU checked, so I unchecked it, but all it did was switch the 100% usage from CPU #0 to #1 in Windows Task Manager.
There is just one miner in guiminer.exe, the default one using the NVidia card. Both CPU Affinity checkboxes are unselected, there is nothing in the Extra flags box. So it looks like mining happens both on the GPU and the CPU, with a slightly lower MH/s rate compared to when it mined on the GPU only.
Strangely, both bugs appeared at the time BitDefender reported a Trojan in guiminer\miners\ufasoft\bitcoin-miner.exe and deleted the file. I also inadvertently launched a second guiminer.exe process at about the same time (because the first one was not visible in the Notification area by default) which apparently resulted in 2 guiminer processes running each half the MH/s rate than the previous unique process used to run, and I haven't been able to run guiminer normally every since, even after reinstalling with BitDefender disabled.
There is no trace of guiminer or poclbm in my Registry, I cleaned up the Notification Area Icons, deleted and redownloaded guiminer, so I don't know what's happening and how to get back to 0% CPU usage.

Thanks for you hints, it really help me a lot~
