Hey. I liked so much Smath. But I have a problem. It is not vital but if i can solve it i will write my equations very easily. I can't select the unit with "Tab" key. For example when I will write 5*m/s^2 and when pressed "m" it shows me meter to select but for this i must double click to "meter" or press tab. When I double click it works perfectly, but when I press "Tab" for quick input It does not do my job. I use Ubuntu 12.04 with mono 2.10. If someone can help me i will be very pleased.

By the way; I ran program from terminal but it does not produce output.

I can confirm this problem. Using Ubuntu 12.04 with latest mono-libraries.

I have the same problem.
I used SMath on windows in the past, which I learned to use and enjoyed AND the tab key worked for units.
I have become a user of Ubuntu, I am using Ubuntu 11.04 with the latest mono and loaded SMath, the TAB DOES NOT WORK TO INSERT UNITS. It spoils SMath and my interest to use it.

I need a solution, help help!!!!!

I also have this issue with Linux Mint 15.

It seems to be a problem with Mono, I will post the bug on their forum as well.

I have same problem. tab key not work

Interesting, I am using latest Smath (1.5.0.9678).
With latest mono release in Void Linux repository (MONO 6.14.0).
My current setup doesn't have a Tab Key issue.
