unfreeze did not work

In my project I had frozen my BFD3 drum track. The plugin was in a track instrument slot. When I unfreezed, the track remained frozen and I could not perform edits.

Windows Vista 64-bit
Cubase 7.5.20 64-bit

The track has unfrozen, but the edit lock is switched on, switch it off in the track list.

It’s been reported in a few threads already.

Thanks Grim!
