X61s missing screen brightness display?

Anyone else notice that after updating to the latest power manager, the screen brightness display is AWOL? All the other onscreen displays are still there such as the Thinklight and volume status displays. But when I change the screen brightness with function home/end, I no longer get the onscreen brightness level display. The brightness changes OK, just no status display.
I think this happened after I updated the power manager a couple days ago, but I'm not 100% sure. I'm running Vista Ultimate x64.

Try updating to or reinstalling the latest versions of Hotkey utilities and the Lenovo System Interface drivers.

Reinstalled both from fresh downloads.... no joy.
Really a puzzle..... onscreen display works perfectly except for the brightness display.

Try uninstalling the video driver and installing a previous version. Make sure it's the Lenovo driver. The Intel driver will not display the brightness OSD.

I could try that.... I AM using the Intel driver. But I'd rather continue using the Intel driver, although I don't recall right now why it was the better choice.
Note that until a couple days ago, it worked fine.... the OSD displayed the brightness status as it always has. The only thing I have changed is I updated the power manager via system update. I haven't changed the video driver in months.
But I guess I have nothing to lose by trying the Lenovo video driver.... I can always roll it back to the Intel driver.

Well, in one form or another the video driver was the answer. I first let Vista find and install the driver it thought best. That restored the OSD.
I then installed the Lenovo driver from a fresh download (which device manager lists as an Intel driver) and the OSD was still there.
No idea why it worked for months with the Intel driver and then just quit.
EDIT..... I just remembered why I used the Intel driver instead of the Lenovo version. I was having issues with the Lenovo driver crashing when I installed the previous version of Power Manager. Installing the Intel video driver solved it and the OSD worked fine.
Since Power Manager has been updated since that time, it seems to work OK with the Lenovo video driver so I'll leave it alone.
