Idealization freezes

[opfermann]

After loading, filtering, baseline-correcting and idealising a file the idealisation freezes from time to time when you go through the episodes after clicking 'Demo'.
Usually one or more episodes contain the idealisation of the previous episode (screenshots). To get rid of it one can click back and forth through the episodes, i.e. from ep. 170 (wrongly idealised with idealisation of ep. 169) to ep. 169 back to 170 until the idealisation is correct.
It appears that the setting of the dead time is correlated to that issue since it was not possible so far to reproduce the bug when no dead time was set.

To reproduce the problem I used the following procedure:

Load file 180426000_selected.mat

Import: 40kHz SR, ms time scale, pA current trace, V Piezo command, mV holding potential

filter 1kHz Gaussian filter

set baseline to zero -> poly

Idealize: Amplitudes 0, -0.6, -1.24, -1.84, -2.45 and resolution 0.08 ms -> Demo

At episode 18 (screenshot 1) I saw the first time that the idealisation of episode 17 (screenshot 2) was mistakenly used for 18. When I jump back to 17 (screenshot 2) and then to 18 (screenshot 3) the idealisation is correct.
