Disc burning inadvertently paused - what to do??

[itm]

I was burning a 25GB BD-R using Imgburn 2.5.80 (on Windows 10 Pro). I accidentally happened upon a keystroke which seems to have paused the disc burning process. The progress window has gone, the BD-RW drive is no longer being accessed, and the green bar at the bottom of the Disk Layout Editor has a white highlight scrolling across it repeatedly. To the right of the green bar it says 99% (I suspect that is the % full figure for the disc, rather than the progress of the burn?).

Can anyone advise on how I can resume and complete the burning process?

Please ignore this - the disc burn actually seems to have completed!
