There was another thread about this issue either here in WinCustomize or the Impulsedriven forums.
I've been having the same issue only with this latest WB 6.4. Sometimes it'll load at boot sometimes not.
It has been installed, uninstalled, reinstalled. I thought all was well after an install via Impulse last night but the next day it just wouldn't load.
The pointer to the WB help page doesn't address the issue but I wonder is it possible to add wbload to one of the startup areas? I've noticed over the past few releases that WB no longer shows up anywhere in Startup Control Panel's four tabs (HKCU/Run, HKLM/Run, Startup User, Startup common) which means it starts up from some place not easily accessible to me. I'd like to be able to force it to load to see if it fixes the problem.
Since WB 6.4 other issues are cropping up with ugly bold fonts (a result of being given a strange but not the normal Windows Classic theme [fixed]) and menus reverting to XP-style white instead of skin-defined menus/colors I've always had, etc etc. This last one has me puzzled. My browser, SlimBrowser, is now using XP-style white menus. It has always used system/skin-defined colors going back to Win98. After today though the menus are white. I'll be working on that one for awhile.
I may have to revert to one of the archived versions for testing purposes just to confirm if it's a 6.4 problem or not.
