FW243: No vario sound and no page def after started gliding

[kaja78]

I was using FW243 with the same setting (attached) without any issues for few flights. Yesterday after take off, there was no vario sound. Otherwise the vario was working normally for few minutes. I could see all widgets, the values in vario bar seemed realistic. When I started thermaling the thermal assistant page was displayed as expected. Then I started gliding and "white" screen was displayed with some message like "no page def" (or similar, not sure now). I think this happened when the first page (basic) should be autoset. When I switched the vario off and on, all pages were available again.
