An used MDO3012 is on my way…
I've read the messages of Howardlong regarding the crash/hang of his scope.
A new firmware (1.22) was recently published by Tektronix and maybe it fixes this problem even if it's not explictly listed in the fixed bug list.
I'll receive the MDO next week and I'll test the new firmware asap…

Enhancement:
- Added control for readout transparency
Defects Fixed:
- Fixed an issue with CAN bus and zoom with large numbers of packets
resulting in slow performance for pan across record
- Fix an issue where DVM DC Autorange would not settle properly
- Fixed "flicker" between RF manual and peak markers when they
overlap
- Fixed an issue with manual markers not displaying in the correct
location on Frequeny Domain Reference waveforms
- Fixed an issue with Peak markers not working if Stop Frequency was
greater than maximum frequency range
- Fixed an issue with recalling Frequeny Domain Reference waveforms
not drawing in the correct position
- Fixed an issue with channel 4 waveforms saving to Reference when
saving after a single sequence acquisition
- Fixed issue with frequency domain math waveforms being improperly
converted to dBm during save to .csv files
- Fixed issue with Save All with multiple frequency domain traces
causing overwritten data values
- Improved save operation where frequency domain waveforms are
previewed
- Fixed a case where frequency domain units did not match the saved
data by forcing all RF trace data to be saved as dBm
- Fixed an issue where RF saved setups would not properly recall
vertical units
- Fixed an issue with saved References not allowing very small
vertical scales
- Fixed a case where completing an acquisition with Roll Mode on
Long Records could result in the first portion of the waveform
being overwritten
- Fixed an issue with RMS measurement with vertical position moved
away from center screen
- Fixed an issue where measurements would not complete after undoing
an autoset
- Fixed an issue with NPULSECOUNT measurement type not counting
correctly
- Fixed an issue with immediate measurement on math when stopped
- Fixed a case where math units for absolute value were being cleared
- Fixed an issue with attachments for ePrint
- Fixed an issue with AC Coupled Trigger losing trigger with
vertical position changes
- Fixed an issue with a legacy command 'HARDCOPY STARt'
- Fixed an issue with where pan range was locked in zoom mode
- Fixed an issue where an Application Error could appear with Roll
Mode, 5M records, and HiRes acquisition modes. Under these
conditions, acquisition trigger mode is forced to Normal
- Fixed an issue with RF Pre-Amp always downloading cal constants
on attach
- Fixed an issue where RF Pre-Amp is in the wrong state on re-attach
- Fixed incorrect value displayed for digital sample rate
- Fixed an issue where Signal Path Compensation could fail if
run after Diagnostics. An instrument reboot is recommended after
running Diagnostics
- Improved edge trigger alignment for MagniVu on digital channels
Known Issues:
- Previewed spectrum data may save previewed header values instead of
acquired data. This can result in incorrect save file data.
To workaround: save frequency domain waveforms prior to
making changes to horizontal or vertical parameters
