Under Vista 32 SP1 with the current UltraNav drivers (v 9.1.3.7) the process "SynTPEnh.exe" is creating a relatively high CPU load (2%) and is constantly accessing the registry. See here for a typical pattern creating by Process Monitor:
11:45:38.8648734 SynTPEnh.exe 3544 RegCreateKey HKU\S-1-XXX\Software\Synaptics\SynTPEnh\UltraNavPS2 SUCCESS Desired Access: Maximum Allowed, Granted Access: All Access
11:45:38.8649077 SynTPEnh.exe 3544 RegQueryValue HKU\S-1-XXX\Software\Synaptics\SynTPEnh\UltraNavPS2\TrackPointModeFunction SUCCESS Type: REG_DWORD, Length: 4, Data: 17
11:45:38.8649209 SynTPEnh.exe 3544 RegCloseKey HKU\S-1-XXX\Software\Synaptics\SynTPEnh\UltraNavPS2 SUCCESS

11:45:38.8753257 SynTPEnh.exe 3544 RegCloseKey HKU\S-1-XXX\Software\Synaptics\SynTPEnh\UltraNavPS2 SUCCESS
11:45:38.8901752 SynTPEnh.exe 3544 RegCreateKey HKU\S-1-XXX\Software\Synaptics\SynTPEnh\UltraNavPS2 SUCCESS Desired Access: Maximum Allowed, Granted Access: All Access
11:45:38.8902010 SynTPEnh.exe 3544 RegQueryValue HKU\S-1-XXX\Software\Synaptics\SynTPEnh\UltraNavPS2\TrackPointModeFunction SUCCESS Type: REG_DWORD, Length: 4, Data: 17
Can this driver be optimized?
Also, when I use the TrackPoint to scroll in Firefox or in other applications, scrolling is not as smooth as when I use a simple external mouse with a wheel. Moreover, while scrolling with the TrackPoint, the "scrolling cursor" flickers.
