texture IPO curve is absent

May be bug, may be not:

when I animate SIZE or OFS of 2-10 texture channel, I can’t find the animation curve in IPO window, thou the animation is still working, but I can’t edit it visualy.

Could I missed something?

There’s a small window next to the IPO menus button. Enter your channel number in here. IT starts at zero.
