Nothing small, but if you're prepared to do build something more complex: git://repo.or.cz/geda-pcb/pcjc2.git Build from the "local_customisation_no_pours" branch. (With stgit I'm lazy about making "proper" feature branches ;)). Note that I rebase this branch a lot, as it is from a stgit series. I'll send you the PCB layout I've been testing it with privately. Steps to reproduce are: 1. Load the board. 2. Drag the white / black (depends on your theme) circular control on the left hand bar. This is a track-ball. 3. Drag like crazy, perhaps stop for a little bit. Drag again. Eventually it hangs when the full GTT is in use. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
