I think my eyes just melted, because that fixed that problem! Thanks a lot.

Hmm. How difficult on a scale of 1 to 10 do you think this will be?
I'd like to help but I'll have to look at a tutorial of sorts on TTF
to see if I can make head or tails of it. I probably won't understand
a thing lol.

I think adding TTF support to XForms will make it a lot better though.

So it crashed for you too, but in a different way? I am using the
-stable library so it crashed on the 10th or 13th call to
fl_set_object_lsize().

Do you know the reason behind the font-caching? Is it really that slow
to fetch a new font struct that it needs to be cached? I'll go re-read
the code, It'll take me some time to understand the whole logic.

Best regards & thanks

Sunny
