Hi, linux users should have no problem automatically starting mprime with a delay. Just stick "sleep n && " in front of whatever command you use to start mprime; this will cause a delay of n seconds before mprime starts up. For Windows users (Win 9x/ME/NT/2000), I have written a small program which delays n seconds ( 0 < n <= 300 ) then runs an arbitary command. Download (18.6 KBytes) ftp://lettuce.edsc.ulst.ac.uk/gimps/software/DelayRun.zip unpack it & move the executable to some folder mentioned in your execution path - C:\Windows\Command works on most Win 9x systems. Then change the command line (but nothing else) in the shortcut in the startup folder which causes Prime95 to run; precede the existing command with "DelayRun n ", (NB the quotes are not needed, but the spaces are!) where n is the number of seconds you want to elapse before Prime95 is started. DelayRun may be used to launch _any_ program after a suitable delay. It remains resident until the invoked command terminates, but will consume no resources. I'd prefer to avoid that, but the C library on my old version of Visual C++ seems to be broken & the "exec" family of routines doesn't work as advertised. If it is invoked with a "ridiculous" delay interval or no command follows, DelayRun simply prints usage hints and exits. Note that the total maximum length of the command line is 127 characters. Apart from that, there should be no limitations on the use of the DelayRun program. I have placed the program in the public domain, waiving all intellectual property rights. I hope that DelayRun will be of some use to those requiring this facility pending the release of a version of Prime95 with a built-in startup delay option.
