[Ipe-discuss] IpePresenter not showing LaTeX rendered results

[Lukas Barth]

Ah, forget that. I found the mistake. One of my "for good measure" calls
to doc->runLatex() remained in the code, probably messing up the
resources that I set earlier. Fixed now.

I'll try to build a nice patchset against ipepresenter tomorrow. Where
do I submit this? Is there a bugtracker for ipepresenter somewhere? I
only found the repository..

Thanks again,

Lukas
