My steps to reproduce the Frozen Seek Tool bug:

• Get in the car and switch to tuner
• Listen to the radio on my drive to work
• Turn off the car (player now in standby mode)
• Remove the empeg and take it inside
• Plug it in at my desk (mains power)
• Switch to Seek Tool
• Notice it's stuck at 00:00.00.

That's from memory, but I'll try and find time to narrow it down a bit when I get home (where the car and the mains aren't so far apart).
