Unsafe checking of running instance

[Pegolon]

Hi,
I have just had some problems with the code that checks if the destination application is already running. Strangely enough the call to NSTask came not back and the application crashed. After further investigation I have found a much cleaner way to check for running applications. Maybe you want to pull the code into your branch.
Cheers,
Markus

Use NSWorkspace for checking for running instance, instead of NSTask with a shell

Thanks for figuring out the crash. Was it happening on Mac OS X 10.7 or 10.6?

I see that -[NSWorkspace runningApplications] is available from 10.6 and up so we'll have to do two different things based on the OS version.

Did you test this on both 10.6 and 10.7?

Andy,
it happened on both system. Unfortunately the crash was silent, it just did not return from the call. Since my application has a minimum system requirement of 10.6 it did not bother the availability of [NSWorkspace runningApplications].
I have tested my changes in both 10.7 and 10.6.
Cheers,
Markus
