Description Soeren Apel 2014-10-25 20:08:45 CEST 
How to replicate:
- Attach SCPI device
- Start PV
- Load saved session (e.g. isp_atmega88_read_lfuse.sr)
- Switch to SCPI device
- Switch back to saved session

Result:
PV shows the session's channels but there is no data
Comment 1 Uwe Hermann 2016-01-04 00:22:07 CET 
Yep, I can still reproduce this with e.g. rigol-ds and any *.sr file as of today.
Comment 2 Soeren Apel 2016-04-17 22:45:56 CEST 
Note to self: PV needs to perform an aquisition when switching back to the saved session.
Comment 3 Soeren Apel 2016-05-03 19:04:18 CEST 
This bug won't be fixed. The reason is that it would require PV to start an aquisition when a file device is selected. Currently, this is performed only once in the MainWindow class. This is how it should be.

A chance is only needed because PV can currently only hold the data of device at a time because there is only one session. With a multi-window UI, there will also be multi-session, so this limitation will be removed then. Thus it makes no sense to fix this now and revert the change later.
