[Ipe-discuss] Drawing in H2 and S2 before finessing with Ipe

[Arvind Ajoy]

Thank you for an interesting piece of software.

I was successful in compiling the code on a Debian Wheezy system.
However, I find the following behaviour while trying to use the tool :
I need to press the pdf button for any changes I make to appear on the
screen. Is this intended? I find it difficult to use, since I am
unable to see what I am drawing in real time.

Best regards
