I suspect there may be a simple answer to this so I apologise in advance, but I don't seem to be able to activate a dynamic preview for the 'rotate about axis' function in texture mapping. The settings which use a rolling wheel adjust immediately, whereas with the 'about axis' rotation (which uses a sliding pointer) you need a get right out of the appearance manager to see an update. This is obviously no good if you are trying to line up a texture with model geometry.

In this case i'm using cylindrical mapping.

Thanks
