Jim,
When writing Launchpad I faced a similar problem when programs from the Accessories menu were run. In the end I decided it was a bit of a non-starter to lock out Launchpad while the accessories were running, as some people might want to be able to access Launchpad itself (e.g. to change device settings or start another program) while the accessory was running, so I ignored this. To be honest, I don't think it's a wise thing to do anyway - you are in effect killing multitasking or task switching by doing this. Presumably, what you want to do is roughly equivalent to EXEC_W or EW from SuperBASIC, where the calling program is locked out, but with QDT being the equivalent in this case. My only experience of anything vaguely like this was trying to write a Wallpaper (background image) program. The closest I got to solving the problem of an unpickable window was (1) don't use CON channels, just use a SCR for display (or even better, close all channels if the program didn't need to display anything). (2) Have a look at Carlo Delhez's wallpaper program, where IIRC he set up either an unpickable window for image display or a window which was always at the ottom of the pile of jobs. -- Dilwyn Jones _______________________________________________ QL-Users Mailing List http://www.quanta.org.uk/mailing.htm
