I recently tried to use the free Linux version on Mandriva Spring 2008.1
but after several hours struggling I realized that it was just so buggy that it was unusable.
I then downloaded the Pro demo with the intention of purchasing a license (after uninstalling the other version) and it performs better, but in a simple test it fails to display the dimensions against the dimension lines in both normal and print preview.
Also the help system shuts the program instantly.
AMD 64 running 32bit Linux Mandriva 2008.1 with 1Mb ram, nVidia FX5600 Ultra with nvidia driver.
A link directly to the FAQ in the software help menu would be good - especially the demo.
I am new to Linux, so a more detailed installation procedure in the help would have been useful or even a README in the package.
I will try the free version again - maybe a similar problem.
