New submission from Kat &lt;katerinab(a)gmail.com&gt;om>: I created an MSE file with a FAMIX.File entry, which didn't specify a name for it. When I load the model into moose, and then click on "All files (1 file)", I get a debugger window, saying "Unhandled exception: No such file or directory ("UNKNOWN")". When I click terminate, it pops up again; looking in the debugger, it seems to be looping in HandleRegistry>>evaluateWithFullProtection: ---------- component: Moose files: yuv.mse messages: 83 nosy: kat priority: Bug status: unread title: Moose: MSE without file specified -> infinite debug loop ________________________________________________ Moose Bugs &lt;moose-dev(a)iam.unibe.ch&gt; <http://macamis.unibe.ch/trackers/moose/issue63> ________________________________________________
