The symptom is that when I complete certain actions (e.g. change timer, cleanup timers, reboot) there can be a long delay (30 seconds) before the screen changes to show that the action has completed.

I first noticed this when I was running OpenViX 5.2.028 with Simple_Ten_Eighty skin. Rebooting made no difference.

I upgraded to OpenViX 5.2.039. No difference.

I changed skin to Vix Night HD. No difference.

In all cases, if I navigate through the menus but make no changes or cancel out of any change then there is no delay. The moment that a change needs to be applied then the long delay is encountered.

I started to think that it might be a problem with the hard drive, which is a Seagate ST1000LM024 HN-M supplied with the HD51, but recordings are still being made correctly.

Does anyone have any idea what it might be?
