Checksum error came back yesterday. Reloaded V4, crashed. reloaded V4 again. Algorithm error?! Replaced lithium battery again, reloaded V4. Yep, hardware fault. I hope the repair bill doesn't cost much. I'm told it could be capacitors and chips. Few things strike me as odd –

1. Majority of crashing occurs when editing usergroups/saving programs to be flagged by usergroups;

2. Eclipse has crashed a lot more since the lithium battery was replaced a second time. 

3. When the screen autodims, it looks like its "strobing" for a few mins.

4. Turning the knobs on the Space when assigning them to MIDI CC and modulating parameters/hot keys sometimes introduces wierd nasty feedback from the Eclipse's audio outputs.
