errors "mirror" and "rotate" commands

Dear Draft Sight. I paid for a Standard license a few months ago. I need it to draw 2D construction and architectural drawings. Unfortunately, the program works with errors. The "mirror" and "rotate" commands block the program. For objects with a small number of elements, the commands work, but as soon as I want to work with a larger set of lines, the program crashes. Please, send to a repairing patch for the program or new full funkcioning vetsion, Thank you, Zdenek Fikar, email: fikar.zdenek@tiscali.cz
