I don't use any X resource settings, just the following startup file: ;---cut here--- ;- Set up 8 bit display and allocate colors device, retain=2, decomposed=0, pseudo=8 window, /free, /pixmap, colors = -5 wdelete, !d.window ;- Set graphics and widget font sizes device, set_character_size=[6,9] widget_control, default_font='7x13' ;- Ensure IDL 5 XMANAGER behavior is consistent with IDL 4 xmanager, catch=0 ;---cut here--- This gives me consistent results on all Unix platforms. Set the environment variable IDL_STARTUP to the full path and name of the startup file. Note that if True Color mode is desired, replace 'pseudo=8' with 'true=24' in the the DEVICE keywords.

Dear Liam, thank you once again. With device, pseudo=8 I got the same effects. But now it was able to fix the problem: I switched the X server to 32 Mio colors and now everything works fine. Thank you very much for your help!! Harald
