Musescore cannot be started twice
After installing virtual midi ports (Maple Midi Ports), Musescore does not work any more. I get the Reunion example after start but I am unable to change the size of the sheet. Also the paper background has disappeared. I suppose, that Musescore has a conflict with the virtual midi ports. It worked okay using the USB MIdi 1&1 before. I tried the nightly build from today. The first time started, it played the sounds, but then no more. I have reinstalled Musescore sevceral times - no change. Also the nightly built did not play after reinstallation.

It's better to ask for support on the forum. http://musescore.org/en/forum
Your problem might be due to the navigator. See http://musescore.org/en/node/18084
Musescore can't be started twice, I have to restart windows to use it a second time. There is no error message, the task manager doesn't show any pending tasks. I am using Musescore 1.3 under Win7. I am working with the virtual maple cable.
Is it better if you uninstall Mapple? Mapple is known to prevent MuseScore to close. See Known Incompatibilities
Thanks for the answer. The problem is, that I cannot install any other virtual Midi ports on Win7, only Maple works. Midi Yoke says "the program was interrupted before the end of the installation" or something like this. I therefore terminate the pending Musescore Process with the task manager. This is for me actually the easiest way to get around this. I hope it can be fixed. I have no problem to install Midi Yoke on Win XP. Must have something to do with the "Benutzerkonten Steuerung" in Win7. But I am unable to disable this.
