Drawings created with qcad (Community Edition) can be opened with qcad. Selecting the same file in the file browser (Ubuntu 7.10) and asking to open it with qcad results in an error message from qcad that the file cannot be opened:"Please check the file permissions" This is true whatever the file permissions (read write or execute allowed for all ).
What must be done in order to open qcad AND the file in question with the file browser?
