I've been using the Nokia Series 60 MIDP Concept SDK Beta 0.3.1 emulator for some time, as it's the one that works better for my needs. But recently it refuses to work and gives me an "Unable to initialize threads: cannot find class java/lang/Thread" error on startup each time I want to run an app. I believe this started to happen after I installed some other of the more recent Symbian Nokia emulators. I need to use the old emu, so has anybody some clues for what could be the cause of the problem? Any idea is welcome. Thanks in advance
