Hello!I am an scientific user of Sparky. Recently, I installed it in a new computer according to the instructions. However, when I started the software, I found that all the 2-key accelerators did not work. The operating system of my computer is Debian 7.4.0-64amd (with ia-32libs). I dont know how I can solve the problem. Could you give me some directions and help me get it done?Best regards,Chengwei Zhang
