Thx for your response MrJackdaw
Spent ages trying to figure it out, without any luck. Ive moved onto dragging the window instead of mousewheel scrolling, but still looking for an answer to the mousewheel scrolling.
btw its not a window setup that can use an effecient scrollbar. It has one but can only operate it while having mouse pointer on the scrollbar :s
Turbine seriously need to improve functionality of the API. Theres many things ive come across that should work but they just dont make sense.
Take [SetStretchMode] for instance. An image needs [SetStretchMode] if its to be altered in size but in using [SetStretchMode], its FORCED to be visible outside its parent window boundary
