I have written several droplets to run in a continuous loop and send output to the standard out or a log file. However it looks as if only one can run at a time. I can start the first one by double clicking on it and then immediatly double click on the second. But no output from the second one occurs until the first one has completed . Here are two simple pieces of code I was using to test this. Does this mean that MacPerl is waiting on the first one to finish? It seems possible you should be able to run two droplets at the same time. thanks --Mark --- saved as droplet script1 --- #!perl $dummy=1; while ($dummy < 11) { print "script 1-pass $dummy\n"; # also changed this to print into a log file $dummy++; sleep 1; } --- saved as droplet script2 --- #!perl $dummy=1; while ($dummy < 11) { print "script 2-pass $dummy\n"; # also changed this to print to another log file $dummy++; sleep 1; } ***** Want to unsubscribe from this list? ***** Send mail with body "unsubscribe" to mac-perl-request@iis.ee.ethz.ch
