Software locking up when scrolling through EPG

[adm]

In the past few hours I’ve “software updated” to 5.1.22 from 5.1.21

On on pressing the guide button and the graphical EPG for that bouquet appearing the box totally locks up.

Sometimes I can scroll up/down half a dozen channels before the lock up occurs at other times the box is locked up immediately.

The TV picture in graphics still shows the last channel tuned to and there is still audio.

There is no spinning VIX and the box doesn’t respond to any of the buttons on the remote. I have to use the mains on/off switch to reset the box to get any functionality back.

Although enabled there don’t appear to be any crash logs.

This has happened 4 times in a row each with a mains on/off. Just in case of a corrupt EPG file, I have also deleted the EPG via the menu option, allowed 10 minutes for re-population before pressing the guide button but still get the immediate lock up.

I have reverted back to 5.1.021 and don’t see this problem.
