ENB incompatible to ATi Tray Tool?

[CosmicBlue]

Whenever ATi Tray Tools are running, Skyrim crashes to desktop when launching game (black screen for short time or I get into main manu but then crash when trying to load a savegame).
Known bug?
Maybe because of modified d3d9.dll?
Quitting ATT with without undoing changes made by and with it (registry and driver tweaks found under "Advanced D3D Tweaks") and Skyrim runs again.
It's unrelated to OSD or overlay or overclocking.
Maybe special AntiAliasing (EQAA and all that are found at "New AA and AF methods") modes or HighQualityAnisotropicFiltering made available by ATT, but not sure.

[ENBSeries]

May be injector version will fix issue.
