I have tried to open 8 files at once. The program got frozen and I have closed it. After that each time I try to start it the program is popping the following message: "There is a crash report available from a previous application crash. Do you want to save of send this report?". Regardless of my selection (yes or no) the program freezes, becomes darken as a result. I have tried to start it using the terminal and there are no error messages. The version of ubuntu is 13.04 and the version of Draftsight is 13.1.56.
