Saturday Times Prize Crossword 26,190 Monday August 31St 2015

[Vimto]

I really tried but time for some help please. This is Saturday's Times please note.
2 down. Clue: Slight protuberance on tip of nose(5). I have: S?U?N. I think it is SPURN but can't parse unless it's cheek somehow. 26 across. Clue Concealing relationship, start running (9). I have: O???A?I?N. 24 down. Clue: Five-one to Germany-- that shows style (4). I have: ???N. I can only think ELAN but don't why. 17 across. Clue: Was bather panicking at first in flood? (5). I have: S?A?? and finally 18 down. Clue: Textbook's Iron Cross initially appearing in bold (7). I have: ??R?E?T This crossword is a standard too far I fear but help would be much appreciated as would an explanation of why my computer on the AB refuses to print many of the letters I type out. Does anyone else suffer this problem?

spurn -= slight spur (protuberance) N(nose)

[Lie-in King]

Spurn - 'spur' (protuberance) + 'n(ose)' (tip of)
26a Operation (running) - 'open' (start, concealing) 'ratio' (relationship)
24d Vein (style) - 'V' (five, Roman) + 'ein' (Ger. "one")
17a Swam-p(anicking)
18d Perfect (textbook) - 'Fe' (iron) + 'c(ross)' (initially) (in) 'pert' (bold)

I can't help with the disappearing letters, sorry - perhaps a thread in Technology/Computers might bring some assistance? :-)

Thank you all. Have to give the points to Leo on this occasion purely on alacrity but promise vetuste next time.
