TLB 4.2.2 Vista 64 explorer.exe crashes

After 11 days I am still getting Explorer.exe crashes. Though they are far less frequent it does happen from time to time. Mostly the crash occurs during logon or when opening a virtual folder like 'Control Panel'.

I tried using tlbHost and it seemed fine at first but when I right clicked and hit 'Refresh' it crashed. One interesting thing to note is that the 'alpha' REG_DWORD entry at:

Code:

HKEY_CURRENT_USER\Software\True Software\tlbHost\toolbars\1

is marked as 'invalid DWORD (32-bit) value'

No matter what Translucency setting I use the alpha value is invalid. Perhaps this is a place to look into?
