Unfortunately, due to unexpected last minute changes to support the switch to Qt from FLTK, both the Windows and MacOSX binary releases of Aqsis 1.8.0 are broken.
We will be working as fast as possible to address this and release an updated 1.8.1 as soon as feasible.
I will post notification here when it is available.
Apologies for any inconvenience.
Paul Gregory
