Re: Issue Saving a Patch

I figured out what the issue below was caused by. Following on
what IOhannes said it turned out there were too many opened files. To play
files with the Else player~ object I was banging open a file each time
it played. I guess it doesn't close the file after playing and I only had
to bang the player~ object rather than the open command again. It would be
nice if possible to print out a message to the console saying the file is
already open to avoid such crashes . Anyway all is good now. Thanks for all
the suggestions of what may be causing the issue
