koloy, I would appreciate your help, it's an emergency.... I'm going to open a door for a curtain in the basement, but the program is closing, I'm using ide 7[/quote ] Hello, if you are using version 7, the problem you are encountering may be caused by the video card or video card driver. Deactivating -use open GL hardware accelerator- option in Settings / General Settings Dialog and working can solve the problem (after canceling open gl accelerator). Do not forget to close and open the program afterwards.) If the problem is not solved, install the teamviewer program and call us.
