The Lemur editor stop showing up

Hi

The Lemur editor stop showing up at some point. I don’t know what made it so.
I can activate and quit the application. Just the window doesn’t show up. Till it happened, it was working fine.

I remember I could fix it once I deleted 2 files in the “Preference” folder before, but this time I can’t find the files to delete.
What I have changed was Mac OS. It used to be a OS Lepard. Now I am running Lemur on OSX Mountain Lion. I don’t know this might be a cause, but
Please let me know any possible solution to get the Lemur editor back on my computer.

Thanks for any assistance.

Best,

Did you ever solve this? I'm having the same issue. I trashed the preferences but it didn't change anything. I noticed the editor app does open but the window doesn't show up. If i choose minimize the window briefly appears from the top of the screen and animates into the dock.

I, too am using Mountain Lion.

Thanks,
