Hi,
I've had created calculation file .sm in Windows and I've used in this file Arial font.
When I've tried opening such file in Linux (SMath with mono), I had experienced very bad behaving of SMath. There was a maximum using of CPU, parts of calculation wasn't seen, etc... and in the end it wasn't completely any response of software. I needed a some time to discover, that a source of problem was a lack of suitable font.
I think, that it would be better to display text using other fonts, which are available in system or display an adequate information.


Best regards,
WP
